What is electromagnetivity?

I got a definition saying that it is the attraction that an atom has for bonding electrons, but I am not quite getting a feel for it. Can someone provide examples where electromagnetivity arises in applications?

 

I'm not sure "electromagnetivity" is a valid term...

 

Very funny avatar..... I like it!

 

I expect you mean electronegativity ?

o yes my bad, bad hand writing I got in my notebook

 

Metaphorically speaking, the greater the electronegativity, the greater the bullyish greed of the atom for some other atom's valance electrons. Oxygen says "GIMMIE IT! IT's MINE!" and potassium says, "golly, I guess I'll just have to share." Viola, Potassium oxide!

 

All I remember about electronegativity is the 3-D period table used to illustrate property as a function of the elements.
