Bonding. A. Ionic bonds form when anions and cations arise
... Covalent bonds form when it is not possible for electrons to be transferred and so must be shared between atoms. 1. Generally this is the case when two nonmetals bond. The tendency of nonmetals is to gain electrons according to the octet rule, a very easy thing to accomplish when they bond with meta ...
