Explanation / Answer

A)
atomic number of Zn = 30
so, number of proton = 30

charge = number of proton - number of electron
+2 = 30 - number of electron
number of electron = 28
Answer: 30, 28

B)
atomic number of P = 15
so, number of proton = 15

charge = number of proton - number of electron
-3 = 15 - number of electron
number of electron = 18
Answer: 15, 18

C)
atomic number of Ga = 31
so, number of proton = 31

charge = number of proton - number of electron
+3 = 31 - number of electron
number of electron = 28
Answer: 31, 28

D)
atomic number of Be = 4
so, number of proton = 4

charge = number of proton - number of electron
+2 = 4 - number of electron
number of electron = 2
Answer: 4, 2
