Hydrogen exists as three different isotopes. H-1, H-2, and H-3.  H-1 is hydrogen with a proton in the nucleus and exists in nature as H2. This is the most common form of hydrogen.

H-2, also known as deuterium, has one proton and one neutron in its nucleus.

H-3, also known as tritium, has one proton and two neutrons in its neucleus. Tritium is a radioactive isotope.

So while the most common form of hydrogen has no neutrons in its neucleus, other isotopes do.

A question  consists  of  that, why  a neutron is not in the atom of Hydrogen.In the atom of Hydrogen there is not  a “proton-neutron” in the nucleous  as at all elements of table of Mendeleyev, but only one “proton”.This is violate conformity to law and Hydrogen has a right on exceptional nature.Indeed, as there is an only one proton in an atom, there is not a necessity for antihunt influence of neutrons. Really, scientists  will not begin to talk  about  elementary  particles  dogmatically,  because  it  is  a  world  of enormous  transformations  and  interconversions of, being of  anti-particles and  these  concepts  very indefinite.Exceptional nature  of Hydrogen  with  absence of neutron    can  not be  accepted, new hypotheses speak  out therefore, many of them  are absurd.
