Question

in order to form water, each hydrogen atom shares its electrons with the oxygen atom. at the same time, oxygen shares its available electrons with each of the hydrogen atoms. this sharing of electrons creates what type of bond?
ionic
covalent
hydrogen

Explanation:

Covalent bonds are formed by the sharing of electrons between atoms. In water ($H_2O$), hydrogen and oxygen atoms share electrons. Ionic bonds involve transfer of electrons, and hydrogen bonds are intermolecular forces, not formed by electron - sharing within a molecule.

Answer:

B. Covalent
