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.
A proton and an electron, and zero, one, or two neutrons.
Hydrogen! (It's an element, not a compound)
Hydrogen 2 has one proton and one neutron in its nucleus. This is different from Hydrogen-1, which contains no neutrons.
The element hydrogen contains particles of hydrogen only.
One proton, one electron.
one proton and one electron
3 and it is called tritium
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.
H2s
Oxygen and hydrogen are the two ellements that make up water.
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.
Hydrogen is an atom but the hydrogen molecule is diatomic.H is a single Hydrogen atom, and H2 is a molecule.
water is made up of hydrogen and oxygen; two atoms of hydrogen and one atom of oxygen
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.
Water is made of one oxygen atom and two hydrogen atoms per molecule
Hydrocarbon.
hydrogen
Yess it is made up of both hydrogen and oxogen because of its name h2o
It is made up of 2 hydrogen atoms and 1 oxygen atom. :)
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.
Hydrogen atom
No, 2 Hydrogen, 1 Sulphur. H2S
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 not a molecule or a atom it is a compound
