The element Hydrogen .
Hydrogen is the lightest and most abundant element in the universe. It is unique in that it is the only element that does not contain any neutrons in its nucleus. This makes hydrogen an important element in chemical reactions and plays a crucial role in the formation of stars and the universe.
Hydrogen (H) is an element. Hydrogen gas (H2) is a molecule.
hydrogen is but not oxygen
Hydrogen is an element, there will be atom that makes up an element and not element that will turn into another.
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 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.
