why copper and zinc doesn't have M3+ in electronic configuration???

Answers

Answered by starkhan12328

Because it is more energy efficient to have a full lower energy orbital than high energy orbital. 4s has higher energy than 3d when it contains electrons i.e. copper with [Ar] 3d^10 4s^1 configuration is in lower energy state than copper with [Ar] 3d^9 4s^1 configuration.
thank you
