WebThese small molecules are known as simple molecules. Small covalent molecules can be represented by dot and cross diagrams. You need to be able to describe and draw the structures of the following molecules using dot-and-cross diagrams: hydrogen (H 2 ), hydrogen chloride (HCl), water (H 2 O), methane (CH 4 ), oxygen (O 2) and carbon … WebAdd these to complete the diagram (hydrogen atoms only have one electron, so they have no non-bonding electrons). The number of non-bonding electrons is almost always a multiple of two. It is usually much clearer to arrange the non-bonding electrons in pairs, to match the pairs of electrons in the covalent bonds.
