What is the reason for the lesser number of oxidation states at the extreme ends of the transition series?

Options

  1. AToo few electrons to lose or share
  2. BToo many d electrons
  3. CToo many s electrons
  4. DToo many p electrons

Correct answer

A. Too few electrons to lose or share

Step-by-step solution
