Water (H2<span>O) can be </span>called<span> a molecule or a compound because it is </span>made of hydrogen<span> (H) and </span>oxygen<span> (O) atoms. There are two main types of chemical bonds that hold atoms together: covalent and </span>ionic<span>/electrovalent bonds. Atoms that share electrons in a chemical bond have covalent bonds.
