We can determine the electron geometry and bond angle using this:

Electron Regions          Electronic Geometry          Bond Angles

2                                      linear                                    180˚

3                                      trigonal planar                      120˚

4                                      tetrahedral                            109.5˚

5                                      trigonal bipyramidal              90˚, 120˚, and 180˚

6                                      octahedral                            90˚ and 180˚

Step 1: Xe (less electronegative than chlorine) so Xe is the central atom.

Step 2: The total number of valence electrons present in XeCl2 is:

            Group            Valence Electrons

Xe       8A                   1 × 8 e8 e

Cl        7A                   2 × 7 e14 e

Total:  22 valence e

Step 3: Halogens, when not the central atom, form only 1 bond
