The type of bond that forms between two hydrogen atoms is called a covalent bond. This type of bond occurs when nonmetals bond together. The two hydrogen atoms have a valence of one electron each. They both share eachother's electron and it then becomes a more stable arrangement. This type of bonding occurs because both of the nonmetals want to gain electrons. The hydrogen atom will react with another one to form H2, a compound. When the two hydrogens share each of their single electrons, the valence or energy level 1 becomes full. A covalent bond is when atoms share electrons between them, to complete a valence shell. In this case, each hydrogen atom feels the effect of the two electrons shared between them.
