Chemical Formulas, Ionic & Covalent Bonds in Chemistry - [1-2-14]

[@rufusmacck3712]

I took chemistry many decades ago. Forgot most of it. You have reignited my curiosity. Thank you!

[@MathAndScience]

Awesome to hear!

[@truthteller2700]

@@MathAndScience you are one of the best teacher i have ever come across in my life. Thank you

[@B_r_u_c_e]

These lessons should be in every high school and college chemistry student's curriculum.

[@renukajaikaran5779]

Sir, you are the greatest. Thanks a lot for these videos. Thorough explanations.🙂

[@abigailstrydom5154]

Please keep posting these videos about chemistry It helps me so so much

[@MathAndScience]

Will do thank you!

[@samerlailanie8940]

you're a great teacher sir, I see that you place yourself in a student's view that doesn't understand things like this easily thank you.

[@khalillawal377]

I began watching your videos with zero understanding of CHEMISTRY but now... Watching from Africa... precisely NIGERIA. You are the best ♥️♥️

[@YilmaWako-cd1du]

I love the way you explain about the Periodic table to make it explicitly clear. Thanks a lot, and God bless you. Yilma Wako.

[@jeffplunkett5335]

I took two years of high school chemistry and one year of college chemistry. Even so, I forgot a good deal of the material from 50 years ago. Most of my scientific interest has been in physics, so that's further reason for forgetting so much about chemistry. This was an excellent presentation to remind me about bonds. Thank you for the explanation about why ionic compounds are not molecules. Until this lesson, I thought all compounds of two of more elements were molecules, irrespective of the type of bond, but the crystal lattice structure is a good way to understand the nature of ionic bonds. I look forward to your lessons.

[@MathAndScience]

Thanks so much!!

[@jackiec1671]

I just want to say I took your advice and I’m a Chem major now. I think it’s the best decision I’ve ever made. Chemistry is very fascinating and has captured my attention. Thanks for your videos! 😊

[@ahuevo07]

Excellent teaching sir, your explaining makes it easy, not slow, not fast. Thank you for teaching us! I will definitely watch more of your contents :).

[@risaarifah2932]

Thanks!

[@MathAndScience]

Thank you so very much!

[@normangrody9082]

I knew abound the different bonds but never saw it in regard to the left-right relation seen in the periodic table.

[@perezpalenciafamily2209]

I've learned so much from this video. You have an amazing way of presenting this information in a way that anyone can clearly understand it. Thank you for making these videos. I use them frequently to homeschool my children.

[@MathAndScience]

This is awesome to hear!

[@quianadortch6690]

😊I could hug you. You have made chemistry sooooo simple for me, and you explain and break it down very thoroughly. Thank you

[@frankroper3274]

I took a year of chemistry in the eleventh grade and I learned more about the periodic table than I did then in 20 minutes!

[@OmoghettoinUSA]

Thanks again and again. Am here smiling. You made it easy to understand

[@sydneydymant8940]

your videos are SOOOO helpful!! thank you!

[@nanayaaafriyie2845]

If all Professors were like you, we would be getting A many times. Thank you.

[@gorillagaming1117]

Lesson duration is perfect honestly not long at all, thank you.

[@MathAndScience]

Thanks!

[@niyonkuruidrissa2346]

10x for cleaning our big dilemma sir! Much respect ❤️❤️❤️❤️

[@umarmuhammadyahaya7626]

Thank u so much for the lectures sir, u are really making chemistry easy for me to comprehend

[@musicloverchicago437]

You are an excellent instructor. I think I have watched 6 of your videos so far and you are super clear with your explanations and you also add a lot of extra interesting info. I wish I could remember what it was that you said in another video, maybe something about bonding, and it was so cool you actually made my eyes tear up. haha

[@bsmnandhu6660]

What a best teacher you are God bless you

[@MathAndScience]

Thanks so much!

[@wouldbfarmer2227]

Great videos! I have a question w/r to ionic bonds: Salts like NaCl. If all the positively charged Sodium (cation) is attracted to the negatively charged Clorine (anion), then why is it that table salt in a box isn't locked up like a solid? Why are they in particle formation like sand in an hourglass? I have to assume the table salt has other atoms mixed in with the sodium and the chlorine?

[@rohnejati6354]

You are absolutely a great teacher!

[@MelanieGrunder]

Thank you explaining this so well and making it seem so simple.

[@AdityaMishra-gd6vb]

Sir can I write H2O2 as O2H2 in reverse way. Why and why not?

[@mohergenrader2113]

Three chapter test today and in still struggling but every video i watch makes things a little clearer. Oh, it's a double time course, too! What was i thinking?

[@jeffbrown2898]

U are a great professor!!!!!!!

[@michaelrowland-us3he]

I dont understand in covalent bonding the word share. Does this mean the electrons of the 2 atoms go around the other one in a figure 8 shape?

[@AyabongaNgubane-er8qe]

I finally understand chemistry all thanks to you sir thank you so much god bless you 🙏

[@jimoneil4695]

Thank you. You are gentleman and a scholar.

[@mercywashi5468]

Thanks so much for the lessons. I was almost giving up on chemistry. Thank God I found your videos. Am beginning to understand and to like everything I thought was too complex.

[@copewithlove]

Thank you very much for all your lessons.

[@MrSomeotheruser]

Love your videos, learned a whole lot from this one in particular. Thank you for sharing this info.

[@jackieduncan973]

you make so much sense thankyou

[@hanasagarin2788]

Your videos have been so helpful for me, thank you!

[@MathAndScience]

You are so welcome!

[@nasrullahturke4480]

Hi Jason How to we fit the definition of molecule and compound in the case of ionic compound. Because as per the definition two or more atom joined together is called a molecule and when it is only different atom joined it is called compound but it is also called molecule. Then why NACL cannot be called molecule

[@patrickshangwe]

I really enjoyed the lecture 🎉

[@DoniPoni0880]

Thank you so much for the class Professor 🙌

[@angeloson2250]

Sir would kindly explain electronic configuration and atomic orbitals .. please 🙏.. and thank you for the hard work

[@suraprod6420]

Not sure if this will help you Reder to Aufbau principle

[@jeannearc9879]

I wish i had a teacher like him when i was in highschool and college. I just recently gain interest in chemistry since most of ny colleagues are chemistry grad and our job mostly focus on particle synthesis. I'm the only one have Clinical Laboratory Scientist (CLS) degree 😅. N my major doesnt really focused in chemistry much. But, i do understand enough to be able to do my job due to job experience and CLS still science 😂.

[@francismannion7075]

Thank you for an excellent lesson.

[@bushtherapy7655]

Fabulous teaching

[@MaudeyMakes]

Thank you Jason 🙏🏻

[@abdulaikallon11]

Am really enjoying the teaching thk u sir

[@prodanesti]

thank you for all you doing. 🤗

[@ArtisanTony]

Great video!

[@corpushermeticum5377]

Thank you I needed this today !!!

[@tresajessygeorge210]

THANK YOU... SIR...!!! Revision and more...!!!

[@judithreyes4664]

Wonderful explanation Thank yoy

[@rizanz2108]

You are a teacher.

[@kiss0009]

If we look at pure elements like gold or iron and consider a brick of one of them, how do atoms stick together in this brick? It is not chemical bonds but atoms don't fly away like gas.

[@arnulfolegaspi5541]

good teacher thank you sir

[@EggoStar]

He is the best!!

[@michaelrowland-us3he]

Why is it h20 but ch4? Why not oh2 or h4c?

[@corpushermeticum5377]

Thank you so much I need the chemistry lessons 😅

[@shapnilshexagon417]

I will buy 19.99$ for 1 month. But how can I cancel auto billing option?

[@MathAndScience]

You can sign up then immediately cancel yourself or email us to cancel. Then you won’t be billed again but will get the first month you paid for.

[@kenh9508]

That was amazing!

[@havegenerosity343]

Thank you so much

[@theandrewgreen]

Where were you when I was in high school🤣🤣🤣love your lessons

[@milliemolina6570]

Thank you professor, now I’m ready for my exam ❤ wish me good luck

[@Blve113]

4:13 help then what is metallic bonds im so confused

[@danab172]

Thank you

[@rohnejati6354]

God bless you!!

[@sotecluxan4221]

[@brucewinningham4959]

Do I understand the following Correctly? All Crystals contains Lattices. If NO Lattice = NO Crystal? Can a Lattice exist and Still NOT be a Crystal? TIA.

[@wilkyclergeot9416]

"Amazing teacher ever, ever and ever for real"

[@MathAndScience]

Awww thank you!

[@antoniescargo1529]

Sodium?

[@nasrullahturke4480]

So basically atom with strong electric force and atom with weak electric force cause the process of gaining and losing the electron and once this process is done based on +ve and -ve charge ionic bond is formed

[@drumtwo4seven]

Nice 👍

[@AdityaMishra-gd6vb]

Why do we care about the angles at which molecule is formed ?

[@MathAndScience]

Lots of reasons, what we are going to learn later is that the actual shape of the molecule including the bond angles is very very important for how the molecule behaves in real life. For instance, the proteins in your body perform their functions, not so much because of what they’re made of but because of the actual shape of the molecule in three-dimensional space. So the geometrical shape of a molecule, including the angles, is actually extremely important and chemistry, and also in biology.

[@AdityaMishra-gd6vb]

Thankyou sir .

[@DieulifortFrancois]

You said 2 metals do not bond; are you familiar with metallic bonding? You also said that an ionic compound is not a molecule; are you aware that all compounds are molecules, but not all molecules are compounds?

[@rachcrittenden2686]

I need to meet and share my life with you! 🎉❤

[@wouldbfarmer2227]

Sodium is inclined to lose an electron and Chlorine is inclined to gain an electron. I am 'inclined' to use 'incline', lol.

[@TheFarmanimalfriend]

should be (NH2)4 not (NH4)2

[@jamespfrancis776]

👍🌷❤👍
