Step method to draw the Lewis dot structure of SF6.
Step 1: Find valence e- for all atoms. Add them together.
Step2: Find octet e- for each atom and add them together.
Sulfur gets 12 electrons since it should make 6 bonds with surrounding atoms.
Step3: Gives you bonding e-. Subtract step 1 total from step 2
Step 4: Find number of bonds by diving the number in step 3 by 2(because each bond is made of 2 e-)
12e-/2= 6 bond pairs
Step 5: Find the number of nonbonding (lone pairs) e-. Subtract step 3 number from step 1.
48-12= 36e-=18 lone pairs
Use information from step 4 and 5 to draw the lewis structure.
Lewis dot structure of SF6
Alternatively a dot method can be used to draw the lewis
Calculate the total valence electrons in the molecule.
Put sulfur in the center and five fluorine atoms on the sides.
Put a pair of electrons connecting the side atom with central atom.Pur remaining electrons on the side atoms.Make sure each side atom get 8 electrons to get octet state.( Sulfur get expanded octet state of 12)
