7. Magnesiaum
Lambang atom = Mg
e = Z = 12
n = A - Z = 24 - 12 = 12
Z = 12
Lambang = ²⁴Mg₁₂
8. Nama atom = Kalium
e = Z = 19 p =
Z = 19 Z = 19
Lambang = ³⁹K₁₉
9. Nama atom = Bromine
Lambang atom = Br
e = Z = 35
p = Z = 35
n = A - Z = 80 - 35 = 45
Z = 35 A = 80
10. Nama atom = Krypton
Lambang atom = Kr
e = 36
p = Z = 36
n = A - Z = 84 - 36 = 48
Z = 36 A = 84
