Vedclass · Answer

(C) The stability of an electronic configuration is determined by the exchange energy and symmetry of the orbitals. Half-filled $(d^5)$ and completely filled $(d^{10})$ $d$-orbitals,along with filled $s$-orbitals,provide extra stability. In the configuration $[Ar]\, 3d^5\, 4s^2$ (which corresponds to Manganese,$Mn$),the $3d$ subshell is exactly half-filled $(d^5)$ and the $4s$ subshell is completely filled $(s^2)$. This specific configuration is exceptionally stable,allowing the element to exhibit a wide range of oxidation states,with $+2$ being particularly stable due to the loss of $4s$ electrons leaving a stable $d^5$ core.

Which of the following electronic configurations is associated with the highest stable oxidation state?
