Hydrogen H+ ion is (i.s.o. 'can be thought of as ...) one proton.
If hydrogen had a neutron, it wouldn't be hydrogen; it would be deuterium. If it had two neutrons, it would be tritium.
An atom is larger than a neutron; a neutron is a part of any atom except a hydrogen atom.
hydrogen-1 atom
1 proton and 1 neutron
The neutrons of an atom are located in the nucleus (except hydrogen-1 isotope which has no neutrons).
protons
Hydrogen-1, (there is a trace of hydrogen-2 (deuterium) found in nature, and hydrogen-3 is an artificial isotope)
a Proton. A hydrogen-1 atom (the most abundant isotope of hydrogen) has no neutrons and only 1 proton. So the atom is 1 proton and 1 electron. So the ion, when the electron is removed, the entire ion is just 1 single proton.
If hydrogen had a neutron, it wouldn't be hydrogen; it would be deuterium. If it had two neutrons, it would be tritium.
An atom is larger than a neutron; a neutron is a part of any atom except a hydrogen atom.
The proton and the neutron make up most of the mass of a hydrogen-2 atom.
Hydrogen.
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.
hydrogen-1 atom
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.
DEUTERIUM ,it is 2nd isotope of hydrogen atom .It contain one proton and one neutron in its nucleus and one electron in it outer most shell . It is also known as (heavy hydrogen)
Hydrogen does not have any neutrons unless it is the isotope deuterium ( 1 neutron) or tritium (2 neutrons)
