f$)$ Which of the following is the electronic configuration of an element with a maximum oxidation state $+5?,(1$ mark$)$

$1s^{2}2s^{2}2p^{6}3s^{2}3p^3$

$1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}3d^{7}4s^{2}x$

$1s^{2}2s^{2}2p^{6}3s^{2}3p^1$

$1s^{2}2s^{2}2p^5$

Mark $0\mathrm{.}00$ out of $10\mathrm{.}00$

The correct answer is: $1s^{2}2s^{2}2p^{6}3s^{2}3p^3$
