He is usually given credit for its discovery as an element.In 1783, Antoine Lavoisier gave the element the name hydrogen (from the Greek hydro meaning water and genes meaning creator)when he and Laplace reproduced Cavendish's finding that water is produced when hydrogen is burned.
Much of the interstellar hydrogen is in the form of neutral atoms (called HI in astronomical terminology) or diatomic molecules (H$_2$), but some is ionized. The singly ionized hydrogen atom H$^+$ is referred to as HII, doubly ionized oxygen O$^{++}$ is called OIII, etc.
