Writing Lewis Structures for Covalent Type compounds(i.e., covalent & polar covalent) 1. A lone atom in a molecule is taken as the central atom to which the other atoms are initially single-bonded to. 2. Total the valence electrons of all the atoms in the compound. 3. Subtract the total number of electrons used to make all the single bonds in the compound in Step 1 from the total valence electrons in Step 2.

Unformatted text preview: to the peripheral atom(s) to form an octet of electrons about peripheral atoms. If the central atom does not have an octet of electrons, form double or triple bonds between the central and peripheral atom(s) by moving electron pairs from the peripheral atom(s) between the central atom and the peripheral atom(s). 5. If correctly done, each atom in the compound should have an octet of electrons about itself, except hydrogen....
