Each isotope of each element has an Atomic Mass number. The atomic mass numbers for hydrogen are 1, 2 and 3. That's because hydrogen has three isotopes. "Regular" hydrogen has a single proton in its nucleus. It's atomic mass is 1. There is also heavy hydrogen, which has a neutron bound to the proton in its nucleus. It's atomic mass is 2. Heavy heavy hydrogen has two neutrons bound together with the proton. It's atomic mass is 3. A link is provided to the Wikipedia article on hydrogen.

What is the atomic number and mass number of deuterium 2H?
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.
What is the atomic mass number of hydrogen -3?
Hydrogen is a non meta element. Atomic mass of it is 2.
Does atomic number equal atomic mass?
No. Atomic mass is the atomic number plus the number of neutrons. The only exception to this is the most common isotope of hydrogen, which has 1 proton and no neutrons, thus both the atomic mass and number are 1.
What is the atomic number the atomic mass and the number of neutrons of the element hydrogen?
The 'standard' hydrogen atom has atomic number 1, atomic mass 1, no neutrons. Although there are 2 other isotopes of hydrogen: - (cant confirm name) which has atomic mass 2 and 1 neutron. - (cant confirm name) has atomic mass of 3 and 1 neutron. All isotopes have atomic number 1.
What is an atomic mass number?
Atomic mass and atomic number are two different things. Atomic mass is the mass of an atom compared to that of hydrogen. The atomic number is the atom's position in the periodic table. It's also the number of protons it has.
What is hydrogen's atomic mass number?
Hydrogen is a gas. Mass number of it is 2.
