Answer

Given,

Atomic number (Z) = 16 and

Atomic number = number of protons in the atom of an element.

Hence, number of protons = 16

Mass number (A) = 32 and

Mass number = number of protons and neutrons

Hence, number of protons and neutrons = 32

Number of Neutrons = A – Z = 32 – 16 = 16
Hence, Number of Neutrons = 16
