Non-metals can exist as molecules formed from covalently bonded atoms or in the case of carbon and silicon giant covalent lattices.Simple molecules are small groups of atoms held together by strong covalent bonds.Non-metal particles can be:monoatomic (single atoms with no covalent bonds) such as the noble gases He, Ne, Ar, Krdiatomic molecules such as N2 O2 H2 Cl2polyatomic molecules such as glucose C6H12O6 or water H2 Omacromolecules such as proteins and DNA, which are very large molecules rather than simple molecules.
