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.
I am not getting it that from do neutron come in hydrogen nucleus... hydrogen is an element which has got no neutron in its nucleus...confused...:P
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.
