No. Although hydrogen is an atom, it doesn't exist by itself (except as an ion). Hydrogen gas is a hydrogen molecule made of two hydrogen atoms.
Hydrogen gas is an element because it is composed only of hydrogen atoms.
Hydrogen is not an elementary gas; hydrogen has a diatomic molecule, H2.
Hydrogen
The element hydrogen is in the gas phase at standard temperature and pressure.
It is simply called a molecule of an element. (ex: O2 is oxygen gas, H2 is hydrogen gas)
Hydrogen gas is an element because it is composed only of hydrogen atoms.
hydrogen gas is H2 so it only contains hydrogen. therefore it is an element
Hydrogen (H) is an element. Hydrogen gas (H2) is a molecule.
Hydrogen is known as a element and a compound. Hydrogen is a light element with one proton and a gas compound with two hydrogen atoms.
Hydrogen is not an elementary gas; hydrogen has a diatomic molecule, H2.
helium is the gas which makes most of the sun

Hydrogen
No. Hydrogen gas is an element, making it a pure substance.
the simplest element. Hydrogen is a gas, a non-metal, it is the lightest element.
Yes, hydrogen gas is a compound. It is made up of molecules which consist of two atoms of hydrogen, an element. It just happens that the same name is used for the gas as for the element.
elementHydrogen as a gas, plasma, or liquid is still an element.
