All isotopes of hydrogen contain one proton. The single thing that makes each element unique is the number of protons in its nucleus. Only that. Neutron count can vary with different isotopes of an element, and electron count can vary as we see an atom loan or borrow electrons. Proton count always identifies an element, and nothing else. The word "isotope" means the same element, with the same properties, but with different numbers of neutrons. Most hydrogen atoms have one proton and no neutrons. Deuterium is the isotope that has one proton and one neutron, and tritium has one proton and two neutrons.
Hydrogen with oxygen forms water; deuterium and oxygen forms "heavy water". Tritium is radioactive, and decays into helium-3.

What is the difference between a hydrogen atom and a hydrogen molecule?
A hydrogen atom is made from 1 hydrogen atom while a hydrogen molecule is made by 2 hydrogen atoms in a chemical compound thus making it twice as big too.
What is the formula for a molecule made up of two hydrogen atoms and one sulfur atom?
H2s
What two elements is water made up of?
Oxygen and hydrogen are the two ellements that make up water.
How come 1 hydrogen is positive and two bonded hydrogens are neutral?
Hydrogen has a valency of one, meaning that a lone hydrogen atom is looking to pair up with one other atom of something-or-other; until it does, it has a positive electrical charge, but once that atom has paired up with another hydrogen atom (which will have also had a positive charge) the valency of both is satisfied, & so the bonded pair become neutral.
What does the atom of ammonia consist of?
One ammonia molecule is made of three hydrogen atoms all singly-covalently bonded to a central nitrogen atom; the nitrogen has two unbonded electrons.
What is water made up out of?
water is made up of hydrogen and oxygen; two atoms of hydrogen and one atom of oxygen
Do hydrogen have atom?
Firstly, atom made up of nucleus and electrons. More atoms join up to make a molecule. Hydrogen is made up of bunch of molecules form by 2 Hydrogen atom join together. Basically, Hydrogen is the atom. If you are still unclear bout that, you might want to google it, shouldn't be hard to find. Good luck.
What compound is made up of two hydrogen atoms and one oxygen atom?
Water is made of one oxygen atom and two hydrogen atoms per molecule
What compound made up of carbon hydrogen and oxygen atom?
Hydrocarbon.
Which substance is made up of only one kind of atom?
hydrogen
Is water made of hydrogen and oxygen atom?
Yess it is made up of both hydrogen and oxogen because of its name h2o
What is water h2o made of?
It is made up of 2 hydrogen atoms and 1 oxygen atom. :)
What is the difference between a hydrogen atom and a hydrogen molecule?
A hydrogen atom is made from 1 hydrogen atom while a hydrogen molecule is made by 2 hydrogen atoms in a chemical compound thus making it twice as big too.
The hydroxyl group is made up of an oxygen atom and an blank atoms joined by covalent bond?
Hydrogen atom
Is a molecule of hydrogen sulphide made up of 1 hydrogen atom and 2 sulphur atoms?
No, 2 Hydrogen, 1 Sulphur. H2S
What does water and oxygen make up?
Oxygen is made of a oxygen atom and water is made out of a oxygen atom and two hydrogen atoms. When combined under the right conditions, hydrogen peroxide can be formed (H2O2).
Is water a atom or a molecule?
Is not a molecule or a atom it is a compound
