The central Xe atom in the XeF4 molecule has 2 unbonded electron pair(s) and 4 bonded electron pair(s) in its valence shell.
Xenon is the element with the following electronic configuration:
[Kr] 4d¹⁰5s²5p⁶
- As we can see there are 6 electrons in the p block of its outer orbital
- it means Xenon has 6 bonding electron pairs, therefore the electron geometry of octahedral
- two of the pairs of electrons on the central atom are unbonded, or lone pairs therefore the molecular geometry is square planar.
- four pairs are bonded in its valence cell.
Thus, The central Xe atom in the XeF4 molecule has 2 unbonded electron pair(s) and 4 bonded electron pair(s) in its valence shell.
