The number of neutrons in a hydrogen atom will depend on which isotope of hydrogen we consider. Not all hydrogen atoms have the same number of neutrons. The vast majority of hydrogen atoms (over 99.98%) have no neutrons at all. Some have 1 (and this is called deuterium) and some have 2 (called tritium). These two isotopes occur naturally but are rare, as can be seen.

To determine the number of neutrons in an atom, you must use the mass number, which is the sum of the number of protons and the number of neutrons. Since the atomic number of the element (for H, the atomic number is 1) tells you the number of protons, you can find the number neutrons by subtraction.

See the Related Questions to the left for how to count the number of protons, neutrons and electrons in any atom of any element.
