Explanation:

Step1: Find protons for Ga³⁺

Gallium (Ga) has an atomic number of 31, so $\#p^+ = 31$.

Step2: Find electrons for Ga³⁺

A +3 charge means 3 electrons lost: $\#e^- = 31 - 3 = 28$.

Step3: Find protons for Se²⁻

Selenium (Se) has an atomic number of 34, so $\#p^+ = 34$.

Step4: Find electrons for Se²⁻

A -2 charge means 2 electrons gained: $\#e^- = 34 + 2 = 36$.

Answer:

For $\text{Ga}^{3+}$: 31, 28
For $\text{Se}^{2-}$: 34, 36
