Lewis structure of TeF4

Step method to draw lewis structure of Tellurium tetrafluoride

Step 1: Find valence e- for all atoms. Add them together.



Step2: Find octet e- for each atom and add them together.



*Te gets expanded octet to facilitate the formation of 4 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-)

8e-/2= 4 bond pairs

Step 5: Find the number of nonbonding (lone pairs) e-. Subtract step 3 number from step 1.

34-8= 26e-=13 lone pairs

Use information from step 4 and 5 to draw the lewis structure.

Lewis dot structure of Tef4

Alternatively a dot method can be used to draw the lewis structure.
Calculate the total valence electrons in the molecule.


Put Tellurium in center and arrange fluorine atoms on the sides.Arrange electrons until fluorine atoms get 8 electrons.( Tellurium gets 10 electrons, which is an expanded octet)
