Work Step by Step
a. Z = 17, A = 35
Protons = 17 (same as atomic number)
Electrons = 17 (assuming a neutral atom)
Neutrons = A − Z = 35 − 17 = 18
Element: Chlorine (Cl)
b. Z = 14, A = 28
Protons = 14
Electrons = 14
Neutrons = 28 − 14 = 14
Element: Silicon (Si)
c. Z = 92, A = 238
Protons = 92
Electrons = 92
Neutrons = 238 − 92 = 146
Element: Uranium (U)
