The type of bond that forms when two nonmetal atoms get close enough for their orbitals to overlap is called a covalent bond. Because both of these atoms are nonmetallic, neither atom has enough electronegativity to give up an electron to each other. What the atoms do, is the overlap their orbitals. The electrons in the shared orbitals can be considered to be in a covalent bond. They are held together by the attraction of both nuclei to the shared electrons.
