It can contain 2 valence electrons.

A hydrogen atom has one proton, one electron, and zero neutrons.
No, a Hydrogen atom does not contain any neutrons. It only has one proton and one electron.
One hydrogen atom contains one proton and one electron.
No; water is H20 and therefore consists of one carbon and two hydrogen atoms.
H2O means two atoms of hydrogen and one atom of oxygen.
Hydrogen H+ ion is (i.s.o. 'can be thought of as ...) one proton.
H symbolises one hydrogen atom. H2 symbolises two hydrogen atoms bonded together or sharing electrons. They are the same because they contain only one type of atom: the hydrogen atom, one proton and one electron
A hydrogen molecule only consists of one hydrogen atom, while a hydrogen atom consists of one proton and one electron while in its atom state. When it ionises it gains another electron to have a full inner shell of two electrons. The most common isotope of hydrogen has no neutrons but can have an isotope with one neutron.
H20 contains three atoms - two hydrogen atoms and one oxygen atom. HCl contains two atoms - one hydrogen atoms and one chlorine atom. This is all due to valency (how many electrons an atom wishes to gain, lose, or share to form a more stable energy state), which varies from atom to atom.
A water molecule consists of one oxygen atom and two hydrogen atoms. The oxygen atom has several neutrons; the hydrogen atom typically contains none. A small percentage of the hydrogen atoms are deuterium or tritium, which do contain neutrons.
