In some molecules and polyatomic ions, the sum of the valence electrons is odd and as a result the octet rule fails. a. True
b. False

True

Explanation:

as electronegativity difference increases, bond length decreases. when a metal gains an electron, the process is endothermic. ... atoms surrounded by 7 valence electrons tend to lose electrons
