# What is the electron geometry of xenon tetrafluoride XeF4?

The geometry of $X e {F}_{4}$ is square planar.
There are $8 + 4 \times 7$ $=$ $18 \text{ electron pairs}$ to distribute over 5 centres. An $A {X}_{4} {E}_{2}$ structure where the lone pairs are trans-axial is the most stable electronic configuration.
