e. beryllium and nitrogen be n

Explanation:

Step1: Determine beryllium ion charge

Beryllium is in group 2, loses 2 electrons, so charge is $2+$.

Step2: Determine nitrogen ion charge

Nitrogen is in group 15, gains 3 electrons, so charge is $3 -$.

Step3: Determine chemical formula

To balance charges, we need 3 beryllium and 2 nitrogen atoms, formula is $Be_3N_2$.

Answer:

Ionic charges: Be $2+$, N $3 -$
Chemical formula: $Be_3N_2$
