Hydrogen has three isotopes.

One is protium, second deutrium, third tritrium.

Protium is the only hydrogen isotopes whose abundance on the earth--- is more than that of the other two isotopes.

And by default we always consider protium has one proton n one electron and so it's mass is 1g.

Whereas, deutrium has one nuetron, one proton, n one electron and hence it's mass is 2g.

And, tritium has two nuetrons, one proton, one electron. Hence it's mass is 3g.

Basically.

Atomic number means the number of protons or the number of electrons present in an atom.

Hydrogen atom carries 1 electron as well as 1 proton.

Atomic mass means sum of number of Protons and No of neutrons.

As the atomic mass of the H atom is 1, It has no neutron present in the atom. :).

In chemistry, the term proton refers to the hydrogen ion, H+. Since the atomic number of hydrogen is 1, a hydrogen ion has no electrons and corresponds to a bare nucleus, consisting of a proton (and 0 neutrons for the most abundant isotope protium 1 1H).

The atomic mass of H is 1 and the atomic number of H is 1 because we know that A.NO = no.of proton.

Hence in H 1 proton is present but not newtron because A. Mass = no.P+no.N. There are A.M. is 1 and no.P is 1, Hence no.N is zero.

Hydrogen contains only one Positive Charge in its Nucleus i.e., contains only one Proton. Number of Positive Charges in equal to its Number of Protons in any neutral atom. So, Hydrogen contains only one Proton in its Nucleus.

The Atomic number of an element is same as its proton number, and also as its electron number, but only the proton is present in the nucleus. The atomic number of Hydrogen is 1, therefore, the proton number is also 1.

Atomic number of H atom is one, it is the top element of periodic table. So atomic mass is one, that is proton &neutron is zero because in 1st proton come then neutron in atomic model.

So, proton =1.

Hydrogen is the first element in the periodic table. It's atomic number is 1. That means it is having one proton in nucleus and one electron in its shell. So it is having one proton in the hydrogen atom.

Hydrogen is top most element in periodic table with atomic no.1 so here we are considering only nucleus that contains only 1 proton. That's why when hydrogen loses its electron we call it ''proton''.
