Answer: proton number = 16
Electron number =16
Neutron number =16
Explanation: Mass number = 32
Atomic number = 16
atomic number = proton number = 16.
Since the atom is neutral, proton number is the same as electron number i.e Electron number = proton number =16
Mass number = proton + Neutron
32 = 16 + Neutron
Neutron = 32 — 16 = 16
