Same rules apply, at the end they get brackets and a chargeġ. Now they all have an octet, it cleans up like this It now has a double bond instead of a single bond.Ĭarbon has 6 electrons, so move 2 from the other oxygen It will share 2 pairs of electrons instead of 1. We need 8, so move a pair of electrons from the O to between the C and O. The carbon has 2 bonds (2electrons) for its 4.? We have 16-4=12 more to place.Īll 16 electrons are now in place, count the dots around each O. We have now placed 4 electrons as 2 bonds. This is usually easy, this atom will be surrounded by the others. So C has 4 and O has 6 (x2 ) = 16 valence electronsĢ. Add up all the valance electrons of the atoms involved. The carbon has 4 bonds (2electrons) for its 8.ġ. Starting with the outer atoms add the remaining electrons in pairs until all the electrons have run out.Īll 32 electrons are now in place, count the dots around each F. We have now placed 8 electrons as 4 bonds.

A bond is a dash that represents 2 electrons. Now we create our skeleton structure by placing bonds in. This is usually easy, this atom will be surrounded by the others. Never H.ģ. So C has 4 and F has 7 (x4 we have 4Fs) = 32 valence electronsĢ. How do we draw a covalent Lewis Dot Structure?ġ. Hydrogen is the exception it only requires 2 electrons (a duet) to be stable. Covalent bonds share electrons in order to form a stable octet around each atom in the molecules.
