H2 is an element as it does not include any other elements from the Periodic Table.
It is simply called a molecule of an element. (ex: O2 is oxygen gas, H2 is hydrogen gas)
H2(g) is the compound in the gaseous state in the given reaction.
Neither. Hydrogen is an element, not a compound. Though it normally occurs in the form of covalently bonded molecules.
Hydrogen is an element because it is made up of only one type of atom, which is hydrogen itself. When two hydrogen atoms bond together, they form a hydrogen molecule (H2). So, hydrogen can exist as both an element and a molecule.
An oxide is a compound that contains oxygen and at least one other element that is less electronegative than oxygen.

H2 or hydrogen gas is neither a mixture nor a compound. It is an element because it is only made up of one element which is hydrogen.
Hydrogen (H) is an element. Hydrogen gas (H2) is a molecule.
Non metals only. Can be a compound of a same element throughout like S8 or a compound of C and H2
Aluminium oxide is a compound 'cos it's made of 2 kinds of atoms. If it has to be an element, it has to be made of same kind of atoms like graphite/diamond/H2(gas).
It is simply called a molecule of an element. (ex: O2 is oxygen gas, H2 is hydrogen gas)
LiOH (Apex 2021)
H2 is the elemental form of hydrogen.
An element can be distinguished by only one atom of an element because it has significant properties, while a molecule has to be found by two atoms like O2 and H2.
H2(g) is the compound in the gaseous state in the given reaction.
the subscript 2 after the H indicates that the hydrogen molecule contains two (2) atoms of hydrogen
H2 is the formula of the diatomic molecule of hydrogen.
