A compound with the same element is called a homonuclear compound. It consists of identical atoms bonded together, such as in the case of diatomic molecules like O2 or N2.
H2(g) is the compound in the gaseous state in the given reaction.
The chemical compound H2 is called hydrogen gas. It is composed of two hydrogen atoms bonded together.
Hydrogen is typically found in nature as a diatomic molecule (H2), which is a covalent compound. It can also form ionic compounds when it combines with other elements.
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.

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).
A compound with the same element is called a homonuclear compound. It consists of identical atoms bonded together, such as in the case of diatomic molecules like O2 or N2.
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.
Hydrogen gas is an element because it is made up of only one type of atom, which is hydrogen.
the subscript 2 after the H indicates that the hydrogen molecule contains two (2) atoms of hydrogen
