What is the geometry of XeO₃?

The geometry of XeO₃ is trigonal pyramidal.

Here's a breakdown:

• Central Atom: Xenon (Xe) is the central atom in XeO₃.
• Valence Electrons: Xenon has 8 valence electrons, and each oxygen atom has 6 valence electrons.
• Bonding: Xenon forms three single bonds with three oxygen atoms.
• Lone Pairs: Xenon has one lone pair of electrons.
• Shape: The four electron pairs around the central xenon atom arrange themselves in a tetrahedral shape. However, due to the presence of the lone pair, the molecular geometry of XeO₃ is trigonal pyramidal.

This shape is similar to the shape of ammonia (NH₃), which also has a lone pair on the central atom.
