A hydrogen atom has one proton, one electron and '''zero''' neutrons. Rephrased, the question is: Hydrogen's number of neutrons equals mass number - atomic number.
The atomic mass of hydrogen is 1.00794 Grams per mol. This is the relative atomic mass because it is a weighted average of all hydrogen isotopes. The relative atomic mass of hydrogen is about 1 because the most common isotope contains only one proton and one electron giving it a mass of roughly one gram per mol. This isotope is the most abundant by far comprising 99.985 percent of all hydrogen. Since then other isotopes(hydrogen-2 and hydrogen-3) make up such a small part of the weighted average it offsets the relative atomic mass of 1 by very little.
all atoms have different masses Mass of an atom is due to protons and neutrons present in an atom and number of proton is something that distinguish between atoms, therefore mass of hydrogen is different to the mass number of oxygen, hydrogen's mass is 1 as it has only 1 proton and no neutrons, and oxygen mass's is 16 as it has 8 protons and 8 neutrons.
All hydrogen atoms contain 1 proton each. The mass number of an isotope is defined as the sum of the numbers of protons and neutrons [note correct spelling] in a nucleus of an atom of the isotope. Therefore, hydrogen with 2 neutrons has a mass number of (1 + 2) or 3.
Only if the atom is hydrogen-1! The mass number of the atom is equal to the sum of the numbers of protons, which is the same as the atomic number, plus the number of neutrons. The only non-radioactive atom without neutrons is hydrogen-1.

As Deuterium and Tritium are both merely isotopes of Hydrogen and not elements in their own right, they both have an atomic number of 1, just like Hydrogen (Hydrogen-1). Deuterium (Hydrogen-2) has an atomic mass of 2, and Tritium (Hydrogen-3) has an atomic mass of 3.
