... There are two main types of bonding discussed here. A COVALENT BOND results when two atoms "share" valence electrons between them. An IONIC BOND occurs when one atom gains a valence electron from a different atom, forming a negative ion (ANION) and a positive ion (CATION), respectively. These opposi ...
