Hydrogen has several isotopes, and the average atomic weight for a hydrogen atom is about 1.007 u. Here are the neutron counts for each isotope:
- Hydrogen-1 (Protium): no neutrons
- Hydrogen-2 (Deuterium: one neutron
- Hydrogen-3 (Tritium): two neutrons
- Hydrogen-4 (Quadrium): three neutrons
- Hydrogen-5: four neutrons
- Hydrogen-6: five neutrons
- Hydrogen-7: six neutrons

Protons neutrons and electrons combine to form?
hydrogen atom
How many neutrons have an atom with a mass number of 20 and 11 neutrons?
How many neutrons would it have if it had 11 neutrons? 11.
Is it possible for an atom to have no neutrons?
A hydrogen atom is only a proton and an electron. Beyond that the neutron seems to keep the nucleus together and stable. Maybe a better question is, "What is the difference between a hydrogen atom without an electron and a proton?"
How many neutrons are in a carbon-12 atom?
Carbon 12 has 6 neutrons
How many number of protons in helium?
H2O has 10 protons. Hydrogen has 1 proton, so 2 hydrogen have 2 protons. Oxygen has 8 protons.
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.
