Homolytic fission - each bonded atom takes one of the shaired pair of electrons.
Each atom now has an unpaired electron and is called a radical
Two species of the same type are produced: X - Y -------> X. + Y. (2 radicals)
Heterolytic fission - One of the bonded atoms takes both of the shaired pair of electrons.
Two ions are produced:
The atom that takes both shared electrons becomes a negatively charged ion (anion)
The atom that does not take the shared electrons becomes positively charged ion (cation). X - Y ----------> X+ + Y- (2 ions)
