No problem. I'm happy to hear that you enjoy them.

This was exactly, exactly what i was missing to clear up a lot of unease I felt understanding electricity and magnetism. I cant believe i don't remember this being explained to me in high school chemistry. Thanks.

Thanks so much. Your explanations and graphics are so helpful!

thank you so much! you are doing such a great cause helping out students with bad professors! we need more teachers like you!

Thankyou so much for the work that you put in to your videos!

Great video! Super helpful. I love the Khan Academy videos too but sometimes they just ramble way too much. This was straight to the point and so much easier to understand! Thank You!

Clear explanation, thanks for the info.

I now know where to look for an easy to understand chemistry guide, thank you

Cheers paul, this video is so helpful for my course

Thx that helped me a lot to study for my science test!!!!!!!!!!!!!!!!!!:-)

This was extremely helpful, thank you very much !!

I'm pretty sure this yt channel is the reason I don't fail science. TY so much :)

great work Mr. anderson

He's been mistaken at 4:52 by saying MAGNESIUM instead of MANGANESE, Please put the correction note in the video. Thanks.

Excellent explanations!

Very clearly put, thanks.

I can't help but wonder with all those electrons moving around if electrically induced magnetism has an effect on the physical properties of metallic atoms.

I think metallic bonding is the hardest concept to understand between the bonding of the atoms. I still don’t get how the negatively charged electrons from the valence shell ( sea of electrons) attract to the the atom. Is it attracted to the protons in the nucleus?

That was definitely helpful with such visualisation.

How does one create this GIF on the electron sea model (1:16) on powerpoint? Any ideas?

It was very helpful ! Thank you very much.

at 5:15, isnt Cu suppose to be 4s1 3d10? should that make it more stable hence why it has such a low melting point?

I was never taught this in high school so this was helpful!

yes very helpful thanx and make more vids man

Thankyou soo much!! It was really helpful since i have an exam tomorrow :)

Thanks sir for the explanation.

Great video! Thanks!

you seriously helped me get ahead in class

Loved it! Thanks!

does group 2b also follow an fundamental principle like group 7b except it skips the s orbital completely, filling the d-orbitals before it fills in the s orbital?

Thank you Mr. Anderson - Neo

Supper helpful Thank You Very Much !

sorry could someone explain why the more stable ones e.g Manganese has a lower melting point? Shouldn't it require more energy thus more heat/ higher temperature for it to melt

This is digressing a bit from metallic bonding, but s & p valence electrons undergo MO hybridisation. Is it a property of d & f valence electrons that they do NOT hybridise, but behave differently, resulting in "electron seas" for neutral metals and the formation of ionic bonds that also react with react with ligands? Can it be said that this always applies?

Very helpful video! Though, I would like to point out a mistake. At 4:54, you said Magnesium instead of Manganese.

Extremely helpful thank you soooo much luv your vids may god bless you

Thanks, Neo!

THANK YOUUUU

Instructions not clear. My left leg wont stop yelling at me.

Bozeman Science deserves more views! Great high quality videos, cheers.

This guy is great tho .👌👌

Does having more unpaired electrons make a metal have higher melting point or what? I'm confused. Please Help! Thanks :)

i learn more from these videos than i do from my university prof................

What tools do you use to make these great videos?

I'm still confused at why the melting point goes up and down. :(

really helpful thank you

is metallic bonding happening because the low ionisation energy of metals ?

Sir kindly upload a vid on valence band and conduction band

Why do protons give up their valence electrons to acquire them later from the electron sea?

How can free electrons in metal determine its melting point or boiling point? So, the higher the free electrons in a metal, the higher the melting or boiling point?

you are awesome!

very helpful

this is so cool

This guy is great

who moved their cursor at 0:47

I don't understand the transition metals and why the melting point goes up and down? Sc melting point is 1500 4s is full 3d has 1 free e- there is a 3+charge Ti mp is greater than 1500 4s is full 3d has 2 free unpaired e- there is a 4+charge V+5 mp is greater than Ti 4s is full 3d has 3 free unpaired e- it seems that as u increase the #of free e- the mp also increases? the more free e- the higher the mp. You are adding more electrons in the 3d orbital. BUT if you add a valence electron from Sc to Ti you are also adding one more proton. Is it because there are more bonds to break that the mp increases? but then after V+5 the melting point drops down when you get to Cr The electron does not fill the 4s orbital before it jumps into the 3d instead there are 5 free unpaired electrons in the 3d orbital and only 1 in the 4s. When you get to Mn 4s is full the d orbital is filled with 5 free unpaired electrons so it is MORE stable the mp drops sharply!!! I thought that if the 3d orbital is full this would make the 3d orbital more stable and increase the mp??????????? If Mn is more stable will it not take more energy to melt? Actually, it is the opposite!!! when you get to Fe the 4s is full with 2 e- the first 3d has 2 paired e- the rest of the 3d has 4 free e-. there are 4 free e- total when u get to Co the mp drops 4s is full 3d has 4 paired e- adding e- means that u have only 3 free electrons this trend decreases the melting point is this because there are less free e- so it is easier to melt? what is melting? Ni has only 2 free e-. smaller mp the 4s is full with 2 e- and the 3d has 8 e- the first , second and third 3d shell have 2 paired e- there are 2free e- in each of the 3d spaces. there are 2 free e- total Cu has only 1 free e- smaller mp than Ni the 4s is full with 2 e- and the 3d has 9 e- the first , second and third and 4th 3d shell have 2 paired e- there is 1free e-total the mp decreases Zn has No free e- smaller mp than Cu the 4s is full with 2 e- and the 3d has 10 paired e- the 3d shell is completely full you are moving towards a non metal

Thanks!

wt about the lustrein metals

What if we made nitinol enfuzed armor? that way if it gets dented we can repair it easily.

Why by Cr did u take away An electron for 4s

I have a feeling that this is made from keynote, recorded with quicktime player and edited with Imovie

At 4:20 Zinc melting point is 420... 420Bl4Z31t!!!11!1!!1! Elum3nty C0nFuM3d!!1!1!!111!1!!!

pretty good

4:10 look at zinc's melting point

manganese* 4:54... great video

At 4:52 Mn - stands for manganese rather than magnesium. Careful next time! Remember!

2012 was a vibe

Are you related to Hank?? My dad thinks you two look like brothers

chemistry is physics's younger brother that thought being annoying was cool and so it got ripped and buff in being annoying till by he time it was an elderly person it died doing a push up.

more the stable an atom is,more its melting point is, im i right? if so then why does dis happen

4:52 it's Manganese, not Magnesium

Important

The sea model is an optical illusion i guess because I'm thinking if its bending or not.

GUYS GUYS, my test is in SIX DAYS, and I can't figure out one concept: This seems idiotic to go to a youtube comments section but I've watched videos and am not getting an answer. This question is: Is Isoelectronic an element with a full Valence shell (Grade 11 AP chemistry). PLS help

Very

Yeet hello science class XDXD

*Manganese not Magnesium . . .

LUOA gang?

I was sent here by my teacher.

yuh

Someone send the answers it’s due Friday :)

nothing was understood especially the last minute

Good

All I have to say is, my professor sinks!!!!!!!! You teach he just talks.

man, that Khan guy sucks compared to this

hello i like pancakes is it metallic bond?

When in doubt, go to Matt Damon
