Question

what do u mean by 18 electron rule

Answer 1

The 18-electron rule is a rule used primarily for predicting and rationalizing formulas for stable metal complexes, especially organometallic compounds.

When a metal complex has 18 valence electrons, it is said to have achieved the same electron configuration as the noble gas in the period.
