### 4.15 6th Edition

Can someone explain part b of 4.15? My brain is slipping and I cannot figure it out for the life of me.

4.15 Write the Lewis structure and the VSEPR formula, list the shape, and predict the approximate bond angles
b) TeCL4
Te has 6 e-, Cl has 7e- times 4 = 28e-. 28+6= 34e-. Lewis structure must have 34e-.

Lewis Structure: Te is the central atom, there are 4 Cl's around the Te, they all connect with a single bond.
Each Cl has 3 lone pairs and the bond to Te.
Te has the four bonds to the Cl's and one lone pair.
VSEPR: A is central atom, X is how many bonds central atom has, E is how many lone pairs central atom has.
Te has 4 bonds and one lone pair so AX4E1
Shape: Looking at the lewis structure the shape is SEESAW
Angles:The SEESAW shape has 90 degree angles and one 120 degree angle.
