Answer:Number of proton present in the nucleus of an atom of sulfur is 16.

Protons, neutrons and electrons are subatomic particles of an atom.

Z = total number of protons

Atomic mass of an atom is defined as sum of the number of protons and neutrons present in the nucleus of an atom.

In neutral atom there are equal number of protons and electron.

A = number of proton + number of neutrons

According to question, there are 16 electrons in neutral atom of Sulfur.

in a neutral atom:

Number of electrons = Number of protons = 16

Number of proton present in the nucleus of an atom of sulfur is 16.
