Hydrogen is a non metal element. Atomic number of it is 47.
The atomic number of all elements including Hydrogen is detemined by the number of protons it has for example, Helium's atomic number is 2 because it only has 2 protons.

Hydrogen's atomic number is 1.
The atomic number for hydrogen is 1 and the atomic number for carbon is 6.
The atomic number of hydrogen is 1.

Calcium has the atomic number 20.
Hydrogen is a gas. Mass number of it is 2.
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.

This case is impossible. Hydrogen will always have an atomic number of 1.
Hydrogen is a non metal element. Atomic number of it is 1.
Hydrogen is a non meta element. Atomic mass of it is 2.
Hydrogen's atomic number is 1.
The atomic number for hydrogen is 1 and the atomic number for carbon is 6.
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.
