Atomic number= number of protons. Hydrogen atomic number=1
Hydrogen(H) is the smallest atom that we know of. Its atomic number is 1.
Hydrogen is a gas. atomic number of H is 1.
Hydrogens atomic number is #1.
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.
This is determined by the number of protons in a atom. e.g. carbon has an atomic number of 6 because it has 6 protons.Neutrons are irrelevant to atomic number. For instance:Hydrogen has 1 proton, NO neutrons and has atomic number 1, its isotope Deuterium has 1 proton, ONE neutron and also has atomic number 1.
Hydrogen is a gas element. atomic number of it is 1.
