Step method to draw the Lewis dot structure of ClF3.
Step 1: Find valence e- for all atoms. Add them together.
Step2: Find octet e- for each atom and add them together.
Chlorine gets 10 electrons in order to make 3 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-)
6e-/2= 3 bond pairs
Step 5: Find the number of nonbonding (lone pairs) e-. Subtract step 3 number from step 1.
28-6= 22e-=11 lone pairs
Use information from step 4 and 5 to draw the lewis structure.
Lewis dot structure of ClF3
Alternatively a dot method can be used to draw the lewis
Calculate the total valence electrons in the molecule.
Put Clorine in center and arrange fluorines on the sides.Fulfil octet for oxygen atoms and put remaining electrons on central atoms.
