Hydrogen is not a man-made element but one that exists in nature naturally. It was discovered by Henry Cavendish in in 1766. So the question of "who made the hydrogen" atom is more philosophy then science.
No. It is a compound made of hydrogen and oxygen. An element is not made of any other elements.
Ammonia is not a element. It is a compound (NH4) made up of the elements Nitrogen and Hydrogen.
helium is made
hydrogen has only one proton and one electron. it is the lightest element and is a pure element, which means hydrogen is made of one type of atom (in this case hydrogen atoms)
Hydrogen gas is an element. It is No. 1. (Atomic Number) in the Periodic Table. It is shown with the symbol ' H ' ; not 'h'. A compound is a substance that consists of two or more elements. , e.g. water (H2O). or carbon dioxide (CO2). However, hydrogen gas exists as a diatomic molecule, that is two atoms of hydrogen combined together. It is represented by the chemical symbol ' H2 '. NB Only the Noble(Inert) gases exist as (Monatomic) single atoms. All other gases are 'polyatomic'.
Hydrogen is an element, as it is a pure substance made of only one type of atom. It is the simplest and most abundant element in the universe.
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.
Hydrogen iodide is not an element, but a compound made out of hydrogen and iodine. It is a polar covalent compound.
Hydrogen bromide is a compound, not an element. It is made up of hydrogen and bromine atoms chemically bonded together.
elementHydrogen as a gas, plasma, or liquid is still an element.
Hydrogen chloride is not an element; it is a compound and has no atomic number!
