Question

the box orbital diagram corresponding to s² p³ is 1 2
the box orbital diagram corresponding to d¹⁰ p² is 3 4

Explanation:

Step1: Analyze $s^{2}p^{3}$ configuration

The s - orbital has 1 box and holds 2 electrons with opposite spins. So for $s^{2}$, the s - orbital box has 2 electrons with opposite spins (↓↑). The p - orbital has 3 boxes and according to Hund's rule, for $p^{3}$, the 3 electrons are placed in separate boxes with parallel spins (↑↑↑).

Step2: Analyze $d^{10}p^{2}$ configuration

The d - orbital has 5 boxes and can hold 10 electrons. For $d^{10}$, all 5 d - orbital boxes are filled with 2 electrons in each box having opposite spins (↓↑↓↑↓↑↓↑↓↑). The p - orbital has 3 boxes and for $p^{2}$, according to Hund's rule, the 2 electrons are placed in separate boxes with parallel spins (↑↑).
