Early 2000's.
It is not an element.It is a compound named hydrogen peroxide.
it's an element!
Hydrogen is an element. So the only element in hydrogen is hydrogen.
Henry Cavendish is credited with the discovery of hydrogen in 1766. He identified it as a distinct element and named it "inflammable air."
The element named after a scientist known for his theory of relativity is einsteinium, with the atomic number 99. It was discovered in the debris of the first hydrogen bomb test in 1952.
The element Hydrogen .
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.
In 1776, a British scientist, Henry Cavendish recognized hydrogen as a definite element and he named it as inflammable gas as it burns. The name hydrogen to it was given by a French scientist Lavoisier in 1783.
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.
