The number of neutrons in a hydrogen atom will depend on which isotope of hydrogen we consider. Not all hydrogen atoms have the same number of neutrons. The vast majority of hydrogen atoms (over 99.98%) have no neutrons at all. Some have 1 (and this is called deuterium) and some have 2 (called tritium). These two isotopes occur naturally but are rare, as can be seen.
To determine the number of neutrons in an atom, you must use the mass number, which is the sum of the number of protons and the number of neutrons. Since the atomic number of the element (for H, the atomic number is 1) tells you the number of protons, you can find the number neutrons by subtraction.
See the Related Questions to the left for how to count the number of protons, neutrons and electrons in any atom of any element.

Which of the following subatomic particles are located in the nucleus of the atom?
The protons and the neutrons are located in the nucleus of an atom.
What are the basic particles found in the nucleus of an atom?
In the nucleus of an atom protons and neutrons can be found. All atoms of all elements have protons and neutrons except one isotope of hydrogen.
How many neutrons are in one atom?
The number of neutrons depends on the atom. In general, mass number = atomic number + number of neutrons.
How many neutrons in h-3?
Hydrogen only has one proton. A Hydrogen-3 atom contains one proton and 2 nuetrons. This is because atoms of a certain element can vary in the amount of nuetrons. The're called isotopes.
How many neutrons are in an atom of 18O?
8
Are there neutrons in a hydrogen atom?
No, a Hydrogen atom does not contain any neutrons. It only has one proton and one electron.
How many negatives positives and neutrals do a hydrogen atom have?
A hydrogen atom has one proton, one electron, and zero neutrons.
How many neutrons are in hydrogon?
One neutron per atom of hydrogen.
Atom that has a nucleus with no neutrons?
Hydrogen.
How many valence neutrons does hydrogen have?
It's called a valence electron, and there's 1 for a hydrogen atom
How many protons and neutrons are in the nucleus of a helium-4 atom if it has twice as many protons as a hydrogen atom?
Two and two
How many neutrons on the middle shell of hydrogen?
Their are only 2 shells in the hydrogen atom.
What is the only atom with a nucleus with no neutrons?
hydrogen
What is only atom without neutrons?
Hydrogen
Only atom that has no neutrons?
Hydrogen (H).
How hydrogen atom is different from all other elements?
The hydrogen atom has no neutrons in the nucleus. There is just a proton and an electron.
Which isotope of hydrogen does not contain neutron?
If hydrogen had a neutron, it wouldn't be hydrogen; it would be deuterium. If it had two neutrons, it would be tritium.
