(B) Cerium $(Ce)$ has an atomic number of $58$. Its electronic configuration is $[Xe] 4f^1 5d^1 6s^2$. In the $+4$ oxidation state,$Ce^{4+}$ has the configuration $[Xe]$,which is a stable noble gas configuration. However,$Ce^{4+}$ has a strong tendency to gain an electron to return to the more stable $+3$ oxidation state $(Ce^{3+})$. The reduction reaction is: $Ce^{4+} + e^- \rightarrow Ce^{3+} \quad E^0 = +1.61 \ V$. Since it readily accepts an electron,it acts as a strong oxidizing agent.

Cerium $(IV)$ has a noble gas configuration. Which of the following is the correct statement about it?
