A neutral atom of sulfur has the following characteristics:

Paraphin [41]

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
