Periodicity

006 - Periodicity

In this video Paul Andersen explains why atoms in the periodic table show trends in ionization energy, atomic radii, electronegativity and charge. All of these trends are explained through Coulomb's Law. A brief description of Dmitri Mendeleev and the power of predictability are included.

For people saying that he goes too fast, the beauty of the video is that you can pause and rewind. He's not meant to be your sole teacher on the subject. He's amazing for reviewing or looking at something again if what your teacher said didn't make sense. Like honestly this helps me so much :)

[banaa]

my favourite thing about the way he teaches is that he teaches the reasons WHY things are true, not just what the facts are. it might be a little more complicated but in the end it really helps you actually understand and apply everything

[wilsonpsotka]

Thank you for taking time out of your life to help people learn what their teachers cannot teach them

[Dank_Farrik]

NEED to give you a shoutout. Taking General College Chemistry this semester and your videos are worth their weight in Au. ;)

[Bozemanscience]

Nice catch. Sorry about that. I tried to fix it with annotations.

[jessicaegharevba]

Bozeman you are indeed a life saver I could possibly not having to attend to my other lectures your teaching is simple and straightforward I could even hear your voice in the exam hall .... God bless

Best science videos on you tube so clear and concise. He seems to be able to explain anything.

Did anyone else notice that the reflection on the surface beneath him in this video makes him look like a classical bust?

[sophiarubens]

This video is amazing! My textbook covered periodicity, but Bozeman (as usual) managed to highlight the same important information in a more easily understood manner. Great information and introduction to the applications of the quantum mechanical model!

This was soo helpful!:) I missed a day and a half of my high school chemistry and I missed all of this and was having a really really hard time trying to learn tuis on my own:) thank you:) ill be subscribing!

[lauraherrincontreras]

Thank you! Love how dedicated you are. Keep up the great work.

[keilarivera]

I learned so much more with him than with my chem teacher

[xiiixiiih.]

Hi did you live in Phoenix in 1993-1999

[kasrafk]

Very useful videos. Thank you mr.Anderson

[mk]

a pretty decent presentation, its sure takes a lot of work

[kisho]

How do those trends evolve if temperature and/or pressure change?

[harshitaawana]

You NEED to make more videos for people like us You have no idea how much you are helping us
Thank you so much please make more videos of other topics of chem

[jollyjokress]

Could someone explain why atomic radii increase from the roiht to the left? I mean this should be a decrease of proton numbers and when they contract the radii then why does the radius increase? What am i missing? ;) thx!

[donnadetoll]

I noticed that Og (oganesson) is shown as a noble gas. It was not listed as a noble gas on my periodic table. I looked it up. It was only synthesized in 2002 in Russia and does not occur naturally. Very interesting!

[TheAnaisP]

Still confused!!! ugh why can't I get this :(

[CaliforniaGuys]

Question. Are these ap chem videos still good for the new chem exam?
