When atoms form compounds, the octet rule is not always satisfied for all atoms at all times, but it is a very good rule of thumb for understanding the kinds of bonding arrangements that atoms can make. The octet rule is a result of trends in energies and is useful in explaining why atoms form the ions that they do. The structure shows addition of phosphine and gallium to the alkyne in an E-fashion, with phosphine adding to the substituted carbon of the alkyne. Identifiers CAS Number. michelle8.
