Compounds are substances in which atoms of two, or more, elements are not just mixed together but chemically combined. Chemical bonding involves either transferring or sharing electrons in the highest occupied energy levels (shells) of atoms. When atoms share pairs of electrons, they form covalent bonds (strong). Some covalently bonded substances consist of simple molecules such as H2, Cl2, O2, HCl, H2O and CH4. Others have giant covalent structures, such as diamond and silicon dioxide.
