Answer:

The number of neutrons does an atom of tungsten (W) has is

110 neutrons

Explanation

Atomic mass of tungsten = total number of protons and neutrons in a nucleus of tungsten.

Therefore the neutrons of tungsten = Atomic mass of tungsten- protons of tungsten

Atomic mass of tungsten = 183.84

Tungsten protons = 74

Tungsten neutron is therefore= 183.84 - 74 = 109.84 which is approximate

110 neutrons
