Nomor atom menyatakan jumlah proton. Nomor massa menyatakan jumlah neutron ditambahkan dengan jumlah proton.

Penjelasan dengan langkah-langkah

Na⁺

p = 11

e = 11 - 1 = 10

n = 23 - 11 = 12

Ca²⁺

p = 20

e = 20 - 2 = 18

n = 40 - 20 = 20

Al³⁺

p = 13

n = 27 - 13 = 14

e = 13 - 3 = 10

Fe³⁺

p = 26

e = 26 - 3 = 23

n = 56 - 26

I⁻

p = 53

e = 53 + 1 = 54

n = 127 - 53 = 74

S²⁻

p = 16

e = 16 + 2 = 18

n = 32 - 16 = 16

N³⁻

p = 7

e = 7 + 3 = 10

n = 14 - 7 = 7

C⁴⁻

p = 6

e = 6 + 4 = 10

n = 12 - 6 = 6
