Trends in the Periodic Table

[@annethara]

I absolutely loved the illustrations of the periodic table with dots. It made things a lot easier and convenient to understand. Thank you so much for this!

[@duellchemistry]

I’m very glad you liked it! Thank you.

[@joshushushu]

thank you very much, i owe you my life lmao jk. but really, this is the nicest explanation ever.

[@nicoleescobar8430]

This is the best explanaition I've ever seen

[@stankieewicz6986]

I agree

[@jyothimg1689]

oh just thank you from the bottom of my heart! i actually learnt something, rather than mugging up the textbook.

[@molly4024]

Thank you so much for this I have been trying to learn this for 4 hours with no success but this was really easy to understand. Thanks

[@LaLa-ig5jf]

Bannderson _ how are they a simp?

[@lake_pond1567]

I think they believe that any form of thanks is simping. They are confused because they have never been thanked for anything so they have no form of reference

[@ranjithsivanandham1927]

Even me

[@alexcope4144]

Rewatched my lectures and re-rea my book several times and it made it overcomplicated. Light bulb moment when you said that the other trends followed the first. Makes so much sense now, thank you!

[@duellchemistry]

Yes!

[@belenrodriguez2566]

thank you ! You explained it so well and put everything my teacher said in a better and understanding way. This was really helpful. THANK YOU :)

[@duellchemistry]

Belen Rodriguez Happy to help!

[@professeurtournesol]

Exactly !

graphics are great

[@nullvoid6083]

30 mins before the test and im dying, thank god I found this vidddd

[@crafttyangelo8574]

I wish all teachers had video and audio quality this good. Goodjob, I learned a lot fast and well, keep it up!

[@luvochiya4134]

Your video is short, but your content is immense nor tremendously. I thank you I needed this. I will keep watching it and I will share with my friends whom I have been strangling with in this topic. From South Africa.

[@anshrialch]

Great....this helped me really well

[@bangladeshisoldier5174]

I have searched many video for 8:49.

[@shady-et5lu]

Thank you so much for this. I was sick and couldn't attend the lecture where this lesson was explained. I had a hard time reading through my textbook, this video has cleared so many points and confusion.

[@christinafreddy6749]

Thank you so much, I have a test coming, and was stressing over figuring out the trends, this helped me so much

[@Diya08patl]

Okay so the only reason im going to school is because only then i can get a degree because im doing most of my learning from youtube nd i actually understand

[@amitd1572]

Just loved it.... Superb and crisp explanation.... Saved my hours and higher retention....

[@gabbycamacho4878]

🎯 Key Takeaways for quick navigation: 00:03 Atomic *radius increases from top to bottom within a group on the periodic table, explained by the addition of electron shells. The snowman analogy helps visualize this trend.* 02:09 Within *a period, atomic radius decreases from left to right due to increased nuclear attraction as protons and electrons are added.* 05:22 Ionization *energy increases from left to right across a period, as smaller atoms hold electrons more tightly. In a group, ionization energy decreases from top to bottom, where larger atoms make it easier to remove electrons.* 08:33 Electronegativity *increases from left to right within a period on the periodic table, and it decreases from top to bottom within a group. This trend is influenced by the atom's size and its ability to attract electrons.* Made with HARPA AI

Me watching this in 2023 and having a better understanding😊thank you so much

[@ChopSamaHuh]

Bro thanks so much, this helped a lot. You deserve way more subscribers!! Keep doing what you're doing though, excellent work!👍

[@duellchemistry]

You’re sweet. Thanks Alex.

[@AngelikaUy]

Hi! What app do you use for your animation? I'm a teacher and I'd like to learn how to make my presentation less boring.

[@duellchemistry]

Hi Angelika. Making your presentations less boring is a noble pursuit. Your viewers will appreciate it! I use Apple’s Keynote app on a MacBook Pro to make my animations. I record with Screenflow (which records my face, voice, and screen all at once) and then I can do some screen zooming in the editing phase too. I hope this helps. Good luck!

[@diyapradeep5639]

GENIUS i finally figured this out thnks to you :') tysmm

[@gulnaseem2314]

Thank u soooo soooo much for helping me in this chapter U r even better than our chemistry teacher and now I will not hv to go through the book everytime Thank u soooo soooo much Stay safe I am watching from Pakistan by the way

[@clubanimations1151]

I have a question. Is the reason that the attraction of nucleus subdues the repulsion of electrons because nucleus are concentrated and confined in one space, while electrons are scattered around more singularly?

[@RichardHertz318]

Yes

[@yuvrajr1]

Bro this guy teaches like 8 times better than my teacher, sad that when I do well in my exams because of him all credit will go to my teacher 💀

[@BakeWithUs]

THANK YOU SOOOOOO MUCH. This video helped me cover 3-4 subtopics in few minutes that I thought would take me dayss.

[@jeffreyzhou1824]

at 8:06, why is helium, neon and argon's electronegativity blank?

[@duellchemistry]

These elements almost never participate in bonds with other atoms because they already have their desired amount of valence electrons.

[@owen22998]

Very informative and clear video. Thank you.

[@tnxgaming283]

[@kkumar420]

Absolutely Excellent. Cleared all my doubts.

[@scisarah3770]

I am having quite a bit of trouble understanding why Lithium's electronegativity is so low, could this be explained perhaps? I just did not quite get the explanation. Thank you!

bro he looks like my grade 8 science teacher from two years ago

[@ojasviagrawal8109]

Awesome explanation. Thank you!

[@morganm7656]

when you are saying that the radius is smaller from left to right is that because s effective is stronger from left to right? is that what you are saying with "pulled tightly together" ?? thank you so much for this video!!

[@hussein2040]

Amazing explanations! Thanks alot man this really helped me out

[@nemo3712]

thanks for the clear n quick explanation brah

[@walterosvaldazosmanuvelios5105]

How did you make the animation for this video?? what app are you using?? great video btw

[@chanhayyan7257]

Hi Sir, may I know how do you show metallic character on the periodic table? :D

[@Bella_bellsxx]

Im a middle schooler and we have this as our lesson currently,and i just wanted to ask if lanthanides and actinides also are part of the periodic trend?if so do these properties affect them too?

[@kisho2679]

how much picometers (pm) are the atomic radius of the elements on the 7th period (outermost shell)?

[@nimishapatel8667]

Why do noble gases have electronegativity? they already have full valence shells?

[@DeborahNdungu-pb1xq]

The snowman effect is really helping😂😂😂

If red stands for the elements that really really want an electron, then what does orange stand for?

could you please provide me with this material so I can us it in my classroom

[@dagimYohannes]

which electron affinity is higher CL OR F

[@samuelalekseyevets7789]

i still don't get the valence electrons for the periodic table

[@lucyl15]

periodt

[@Amy-bv6xr]

is electronegativity the same as metallic character or no?

[@duellchemistry]

Amy Coreas Nope. Electronegativity is how much an element wants outside electrons to come to it and join its valence shell. Metallic character is a fancy phrase for “how metally an element is.” Metals exhibit metallic character, metalloids exhibit less, and nonmetals exhibit the least.

amazing images and explanation, I finnaly understood the periodic trends. Thank you so much!

[@annynguyen4386]

Can someone help me fill in the blank please? Ionization energy ___________1__________ down a group. As the size of the atom increases, the distance between the nucleus and the outermost (valence) electrons ____________2__________ and the attraction between them becomes ___________3____________. The weaker the attraction, the ___________4___________ the energy needed to remove the electron from the atom. Ionization energy ________5____________ across a period because the number of protons ____________6__________ and the attraction between the nucleus and the outermost (valence) electrons _________7____________. The stronger the attraction, the more _________8___________ is needed to remove the electron from the atom. In order please, thank you so much!!!

[@lucygrant1851]

Do it yourself

[@Zurgeditz]

the dots really helped

[@leormhandelacruz]

How do you know which element has greater atomic size based on the trend if they are closely the same in size but different in group and period like beryllium and aluminum? Magnesium and Gallium? Thanks for the response.
