Question

In the molecule $XeOF_4$, what is the total number of lone pairs of electrons present strictly on the central Xenon atom?

Answer: 1

💡 Solution & Explanation

Xenon has 8 valence electrons. It uses 2 electrons to form a double bond with Oxygen, and 4 electrons to form single bonds with the 4 Fluorine atoms. $8 - 2 - 4 = 2$ electrons remaining, which constitute exactly 1 lone pair on the central atom.
