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 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!
oxygen an hydrogen
It is not technically 'made of' any elements as it is the element Hydrogen already.
