Evaluate the following generic list of pure transition metal monoxides: . What is the absolute, iden — d and f Block Elements Chemistry Question

💡 Solution & Explanation

The generic formula $MO$ dictates an exact $1:1$ ratio between the transition metal cation and the oxide anion. Because the oxide anion consistently carries a formal charge of $-2$ ($O^{2-}$), the neutralizing transition metal cation ($M$) must mathematically carry a corresponding formal charge of $+2$ to yield a neutral solid lattice.
