    Hydrogen atoms are made up from 1 proton and 1 electron. Hydrogen atoms lose their electron to become \(H^+\) cations, or, more rarely, gain an electron (and have a total of 2 electrons) to become hydride ions \(H^-\). Hydrogen atoms can also combine (in pairs) to form a covalent bond, each H atom puts up an electron to be shared with it's partner. |dw:1444611085929:dw|

    The definition of a molecule is two or more atoms held together by a covalent bond. Hydrogen only has one proton. This means that it can pass that one proton onto another element, making it part of a molecule. It can become an ion if it loses that one proton, or gains another proton. n ion is an atom that has gained or lost one or more electrons. The definition of a molecule is two or more atoms held together by a covalent bond. Hydrogen only has one proton. This means that it can pass that one proton onto another element, making it part of a molecule. It can become an ion if it loses that one proton, or gains another proton.

    "It can become an ion if it loses that one proton, or gains another proton." this is incorrect. Atoms can't exchange protons in chemical reactions to become ions - if an atom gains a proton, it actually changes the type of atom it is. For example if N somehow gained a proton, it would become an oxygen atom.
