Atoms can combine to form compounds, in simple whole number ratios
The atomic mass is determined by the contents of the [atomic] nucleus - the sum of the protons and neutrons; in this case the atomic mass {also called the atomic weight} is 31. A dalton is the mass of a hydrogen atom, or ion: that is, a proton.
The approximate mass is 11. Technically you could express this in units of daltons as 11 Da (Daltons previously called amu, Atomic Mass unit, or as 11 (the dimensionless, relative atomic mass which chemists simply call atomic weight) .

1 proton and 1 neutron is needed because the 2 in hydrogen 2 refers to the atomic mass and protons and neutron have a mass of about 2 daltons each.

protons,neutrons and electrons are the sub atomic particles

It was only accurate when describing the hydrogen atom.
atomic mass for hydrogen is 1.00794.
Hydrogen's atomic number is 1.
1 proton and 1 neutron is needed because the 2 in hydrogen 2 refers to the atomic mass and protons and neutron have a mass of about 2 daltons each.
The difference between a hydrogen atom and atomic hydrogen is that the "hydrogen atom" represents one atom of the chemical element hydrogen. Atomic hydrogen are isolated hydrogen atoms.
The idea that atoms are indivisible.
