Ionic vs. Covalent bonding
04/10/99 Thus far we have looked at when atoms bond due to the transfer of electrons An ionic bond forms when an atom has a greater attraction for e–s than a second atom However, if two atoms have approximately the same pull on electrons, they share the electrons (forming a “covalent” bond) Read “Covalent bonding” and “Covalent bonding continued”.
