When a bond between two atoms is broken, why only one electron is released. Why not two? (as two electrons make up a covalent bond.)

What do you mean by "broken" and "released"? Do you mean ionization? –  Dan Mar 30 '13 at 22:51

I guess , you are talking about electrolysis.. Because electron is usually released during electrolysis. And electrolysis is favored by ionic compounds not covalent compounds. During electrolysis , the atom release the electrons, which are extra for them. It is not a rule that it must be 1. –  newera Mar 31 '13 at 2:02
    
Or I think s\he is talking about semiconductors, creating of holes and electrons after a covalent bond is broken. –  ABC Mar 31 '13 at 11:31
    
@ 007:It's he :-) @all: 007 is right.I was actually reading about BOND MODEL of semiconductors. sorry if this question sounds stupid but I genuinely can't understand this on the basis of what I've been taught at high school –  user22595 May 1 '13 at 8:09
