Your first step should be to analyse the compound. For example, if the compound is carbon, you know it always has a valence of four, so, if it has a formula C2H4 (ethylene) it obviously has a double bond. There are difficulties here because benzene C6H6 can be considered to have 6 1.5 C-C bonds, being aromatic.
An excellent example is diamond, which is pure carbon, with each carbon atom bonding to four others, to form a huge molecule containing many millions of millions of atoms. This shows a part of a diamond molecule: In diamond, all the carbon atoms share one electron with each of their four neighbouring carbon atoms.owever, unlike ionic bonds, there is a limit to the number of covalent bonds to other atoms that a given atom can form. For example, carbon can make four bonds-not more. Oxygen can form two bonds.
