Does a hydrogen atom have neutrons?

Answer 1

The deuterium and trittium isotopes certainly do.

Most hydrogen nuclei have only the 1 nuclear particle: the protium isotope, #""^1H# is certainly abundant, and has no neutrons. However, some hydrogen nuclei contain one or two neutrons to give the #""^2H" deuterium"#, and #""^3H" tritium"# isotopes respectively.
