How many neutrons are in a hydrogen atom?

Solution (By Examveda Team)

A hydrogen atom typically consists of one proton and one electron.

Most hydrogen atoms have no neutrons; they only contain a proton in their nucleus.

However, hydrogen has isotopes like deuterium and tritium that contain neutrons:

Deuterium has one neutron, and Tritium has two neutrons.

Since the question is about the standard hydrogen atom, which does not have any neutrons, Option D is correct.
