Atomic Radius - Basic Introduction - Periodic Table Trends, Chemistry

This chemistry video tutorial provides a basic introduction into atomic radius which is one of the four main periodic table trends you need to know. Atomic radius increases as you down a group and to the left across the periodic table. Atomic radius decreases with effective nuclear charge but increases with each successive energy level added to an atom as you go down a group.

Believe me you are making wonders!!! I have a chemistry test tomorrow ans was hopeless I could learn anything more in couple hours before the test. But I did, and I learned a lot more than I did in several weeks. Thank you very much for your hard work, and please continue uploading your amazing videos. We do learn from them

[zainabalekri]

This is actually easier than I thought! You made it seem easier tbh, thx

[justabouteverything]

I love you so much, my teacher gave me a self learning assignment that will come in a quiz and this literally is saving my life thank you

Professor Organic Chemistry Tutor, thank you for a solid Introduction to Atomic Radius and Periodic Table Trends in AP/General Chemistry. From the practice problems, I found this material simple to follow and understand from start to finish. This is an error free video/lecture on YouTube TV with the Organic Chemistry Tutor.

The fact that you are so popular shows schools are doing what they're supposed to well. Thx anyway bro

[TianaMariieex]

Your videos are helping me feel soo much more prepared for my 1st chemistry exam than when my professor explains it in class. THANK

[Aya_aya]

Thank you, my teacher, may God bless you You are the best teacher ❤❤

[justafrog]

My man JG always has my back when it comes to chemistry

[aphilemdluli]

Thank you so much. You explain everything so well.

Where did you get the PM of every atom?

[ace]

I hope you make a lot of money through ads. Thank you

[chongangulube]

I was getting confused on this, untill I watched this video. Thanks so much JG.

[BeAGdHuman]

I can't thank you enough
God Bless you💜

[nightmares]

How are you figuring out what they are in PM??

[gladysnnabugo]

Thank a lot for ur amazing video it really helped

number of protons in magnesium is twelve in number. On the contrary, the number of protons in iodine is 53. The atomic radius of magnesium is 173 pm and the atomic radius of iodine is 198 pm. Hence,  iodine has a larger atomic radius.

[kyrrajenner]

This was really helpful and detailed 🌚

Ratha use Zeff to distinguish atomic radius between atoms then at the end you will notice that Zeff is inversely related to AR

[qiqi]

Thank you so much! This video is so helpful for me

Why you wrote that in Na atom in the second shell there’s ten electron, but it is 8 electrons, 2s^2 2p^6, am i right?
