Electronegativity Part 2

The following video looks at the Electronegativity of molecules and its trend on the Periodic table. For more video check me out on iTunes by searching "Papapodcasts"

Once again...you save the day !!! You're my hero! Why can't they just teach this stuff in the same manner in college chemistry classes???

@bellybong Thank you for such a nice comment. These positive comments help me realize why I put these videos online. Best of luck with your program. You'll do great.

Hmm on the first slide: Equal vs. Unequal e- sharing, it looks like the atoms in HCl [polar covalent bond] are more closely attracted to each other than the counterparts in LiCl [ionic bondage].

Is there are reason why the non-polar & polar examples are in circles, yet there is a disparity in the ionic diagram?

I just figured since the charge is complete for Li+ and Cl-, this would be more likely to be a circle since they would be more strongly attracted and thus closer each other?

Keep in mind that when an atom loses it valence electron, its radius shrinks because the nucleus has a stronger hold on all the inner electrons. This is why the ionic will show the way it would. Besides, this is more of a simplistic visual of the sharing and gaining/losing of electrons. Hopefully this helped. Thanks for watching. Good luck with your studies.

at 8:08 he draws a kid that is beat up haha but seriously this video was very helpful. Probably be the only reason why I won't fail my test tomorrow

[BOOOOMkidddd]

thank you.

If electronegativity is the attraction for a shared pair of electrons in a covalent bond, then how come it is said that if the E.N. difference is greater than 1.7 the compound is ionic??? This does not make sense because how can there be a shared pair of electrons between a ionic bond.
