Periodic Table Part 10: Transition Metals, Lanthanides and Actinides

With the main-group elements covered, it's time to check out the other sections of the periodic table, those being the transition metals, as well as the lanthanides and actinides. We rarely discuss most of these elements, so what are they all about? Let's find out!

Dave - I know these videos are not your most viewed, but I want you to know that it is incredibly valuable for me and my students. Thank you for creating this useful explanation 😊

[@MichaelLeightonsKarlyPilkboys]

Hi Professor Dave, Just wanted to say I read "Is This Wifi Organic?" a few months ago and loved it. I always struggled with chemistry at school and thought it too abstract and complex for me to understand, but your step-by-step introduction to understanding chemical structures and basic concepts was so clear and concise that it's really sparked an interest in chemistry for me. Going through your chemistry series now and wanted to say you are an excellent teacher. When I was at school, I was always one of the last to understand things in science classes so I kind of wrote it off as something beyond my understanding. However you make it very accessible and fascinating for people like me. Thank you so much for the great videos, they are fantastic.

[@waelfadlallah8939]

Yes we are continuing with the rest of the periodic table elements thank you professor Dave

[@aryanpatel8480]

Hi Dave, I just want to say that I have fallen in love with ur teaching style and mostly at the starting of your video, I absolutely love it.

[@fahimahsan3603]

Your video is much better than any premium subscriptions or coaching I have in this country. Thanks for such amazing contents

[@gabekatze852]

I really love this series

[@abcde_fz]

Every Single Time I see a good video on the Periodic, I learn yet ANOTHER type of information that's contained in it. I can say I got a solid start in Chemistry, ('elective' course at school), but soon found out I wasn't 'getting' a feel for the several different patterns of sub-sets of the atom, (the ones they start to branch out into after getting you comfortable with the basics of Protons, Neutrons, and Electrons). I got the shells, and the importance of the sharing of electrons, we got to something called "valance numbers", and it was right after that I think we started getting intros into more than one system at a time. Where we'd only needed to keep say 5 basic facts in mind for the first month, all of a sudden there was 3 branches with 2 facts each, ... and I couldn't keep up. I'm glad I got the VERY basics out of the way, so that a good video like this CAN teach me something about more nuts and bolts, without having to define "ion" and "atomic number" again. Anyway what was it in here, a chart about "Aubrey" this-or-that? NEVER saw that introduced before, so BACK TO THE FUN OF WATCHING!!!

[@amciuam157]

I love periodic table of elements. How about a video about the island of stability and future of elements research? We are now able to change lead into gold, which was literally the alchemist dream. Albeit the process is expensive and produces tiny tiny amounts, probably less than a few hundred atoms per year.

[@aguyonasiteontheinternet578]

[@ganeshbhantana6815]

This is so beneficial for me because I have to study in our syllabus. Thanks, Dave, as usual, It's a great video so far.

[@sciencenerd7639]

hooray, new chemistry video!

[@rickkwitkoski1976]

Thank you. Informative and concise as usual. That last bit about some people wanting to "believe" something else about elements is so telling in this current time of so much false and mythological garbage being spread around. The Periodic Table of the Elements is so elegant that it almost seems "designed" !!!

[@thewatcher6312]

Very cool, I haven't heard of many of these since waaaaaaaaay back in high school, so I love finding this! So... here's this playlist, and here I am, so I might as well make sure I don't waste a day. 😉 Daddy told me when I was really young (6 or 7) that if I learned something, the day wasn't wasted. I've tried to make sure every day since to not waste a single day! In return, all I have to offer is this like and comment.

[@backtopray7311]

I'd love to see a video about Pyykkö's periodic table

[@marcusscience23]

9:35 Actually, to be more precise, at the start of the f block, an electron is indeed placed in the d subshell instead of f, but later on, that d electron hops to the f subshell, and the d subshell starts filling for real at the start of the d block, right where it’s supposed to.

[@tonymcmayer5944]

For some reason I never noticed that uranium, neptunium, and plutonium are clearly named after the planets.

[@ekantoro9013]

Hi prof dave...do you have video about lanthanide contraction?

[@tx_h]

ah yes someone who can explain stuff better than my school..

Fun fact: Osmium was, as Tungsten (Wolfram in German, hence the W) is nowadays, used for incandescend light bulbs as the glowing parts. That is also how that big company making light bulbs was named - Osmiumwolfram, or short: Osram.

also actually there seems to exist a very long list regarding the huge amount of (potential) applications of Lanthanides and Actinides (aka REEs) in modern technologies ...

[@markshort9098]

Wow i didn't know tungsten has such a tensile strength, i work with a lot of tungsten (machinist) and i know about it's rigidity, heat resistance and hardness but it chips and breaks easy so it never occurred to me that it has such high tensile strength.. i thought professor dave had made a mistake so i had to look it up 🤣 silly me

[@pepperVenge]

Silver is also the best electrical conductor if I'm not mistaken. On a scale of 0 to 100 representing electric conductivity, where 0 is not conducive, copper is at 100, and silver would actually be 105/106. While silver is a slightly better conductor, its far more rare then copper, so copper is most often used in wiring. Gold is at 70 on this scale. While gold is exceptionally more rare then silver, and copper, its often preferred as a conductor in things that have exposed wiring like circuit boards because gold doesn't tarnish like silver and copper do.

[@rheiagreenland4714]

Fun fact: 4 elements (Yttrium, Ytterbium, Terbium, and Erbium) all get their names from the location they were found - in a mine nearby a small Swedish town called "Ytterby." All of these are naturally occurring stable metals.

[@DIANASEVEIN]

Professor Dave, I know it sound ridiculous but can you explain to me the thing that they do in movie action example " the case of the patient is gunshot between their ribs and abdominal the first aider will put some pressure at the wound. But suddenly they can not breath why the first aider need to puncture the clavicle area so that the patient will again breath?" They called it PNEUMOTHORAX? I really don't understand is that POSSIBLE? 😵😵 Please make some explanation professor Dave ☺️

[@mobuildsstuff]

A pierced lung can leak air into the area between ribcage and lung which disconnects it from your breathing motion. Under normal working conditions your lung sticks to the inner surface of your ribcage and in/deflates with your chest movement. Removing the air inside the ribcage mostly fixes the not able to breath part. Yes this can happen, but the treatment usually looks less improvised than most movies show

[@rassimsimou1594]

[@osmiumsoul9535]

I believe carbon has the highest melting point of any element. Dave may have meant highest melting point of any metal. Someone let me know if thats true.

[@tarangjasnani5344]

Solve the jee advance chemistry questions

[@ElithiosX]

Wait, will the transition elements only be mentioned for their organometallic chemistry? So basically organic chemistry with extra steps? I was really excited to see some love given to the inorganic side of chemistry, during my bachelor and masters courses it always felt like 50% organic, 30% analytic, 10% inorganic and 10% physical =/

[@ProfessorDaveExplains]

That's more or less what they're used for, apart from materials science which is a little more of a physics application.

[@richardkeilig4062]

Prof. Dave, what is the name of your book? Rick, Chem.teacher MUHS Dave, the address above is wrong. Please reply here. Thanks, Rick

[@PureSimplee]

Hello Dave, I have a question. I watched a video of a flat earther that showed two different pictures, one had mars photographed by a telescope and it looked very distorted, almost like a star through a telescope, and the other picture had photos of saturn also taken by a telescope which look much less distorted and you can even see the planet's disc, how does that work? Is it because the quality of the telescope, or is it because other factors. edit: or are the pictures of mars literally fake, that can also be an option lmao

[@mobuildsstuff]

Do you have any other information about the photographs? Could be editing, a damaged telecope/sensor, human error or just be something else than described. Flat earthers claim so much, but provide so little information. Seems like they got smth to hide...

[@PureSimplee]

@@mobuildsstuff fair point honestly

[@SodiumInteresting]

I still feel like there could be regions of our universe with different fundamental constraints to ours only we are to be forever causally disconnected from them. There is also potential for us to explore heavier and heavier elements and their isotopes, potential islands of stability previously theorised or other ones weve not even predicted. We won't know until we waste immense resources firing particle beams in the hope of finding them 🤣 Some might be possible in ultra extreme conditions we have no chance of achieving here on earth 🤔 I don't know

Professor, can you cover the topic of *quantum field healing* next? it's a totally legitimate 100% backed by science not-faith healing practice that I just learned about. totally legit.

[@peterboris3765]

At most, he’ll make a video debunking it. Like he has done with stuff like flat earth and “spiritual healing”

[@mobuildsstuff]

Yes, please. And someone can finally explain the magic mystery of those quantum fields and maybe even measure something...

[@kurtvonnegut9959]

He debunked the creator of it a while ago Deepak Chopra in his quantum mysticism video. Watch that. Quantum field theory is a theoretical framework that combines classical field theory, special relativity, and quantum mechanics. QFT is used in particle physics to construct physical models of subatomic particles and in condensed matter physics to construct models of quasiparticles. It cannot be applied in anyway to healing of any human. Sorry Lord Thick Nipples. Quantum field healing is a pseudoscience, says as much on the Wikipedia page dedicated to it.

An 8th period would have even more elements in it. It would have a whole new orbital family available.

[@HugoFilho.]

Yes its predicted than a 5g¹⁸ orbital will appear for 8th period elements so the 8th period should have 2+6+10+14+18=50 elements. From element 119 to element 168
