Question

Mo atom in its ground state has a 4d⁵ 5s¹ configuration and Ag atom 4d¹⁰ 5s¹ configuration. This is because a shell which is half-filled or completely filled is particularly ______.

Options

• strongly destabilized due to higher exchange energies

• weakly stabilized due to higher exchange energies

• weakly destabilized due to higher exchange energies

• strongly stabilized due to higher exchange energies
