Expected Ions of Bi and N

  1. Apr 19, 2010 #1
    This isn't a HW question per se, but it arose after doing a HW problem -- feel free to move if you feel it's necessary.

    I sorted four elements into two categories:

    Those expected to lose electrons (Bi and Ga)
    Those expected to gain electrons (N and Br)

    I'm having difficulties grasping this conceptually -- particularly why Bi and N are in different categories if they both have 5 valence electrons. I understand that N is more electronegative than Bi, but how do you determine when this (electronegativity) will result in a net loss or gain?
