predict whether the xeo₃ molecule is polar or nonpolar. justify your prediction. use lewis structure diagram to justify your prediction.

Explanation:

1. Lewis Structure of XeO₃: Xe (central atom) has 8 valence electrons. Each O forms a double bond with Xe (using 4 electrons per O, total 12 for 3 O atoms), leaving 1 lone pair on Xe.
2. Molecular Geometry: Trigonal pyramidal (3 bonding pairs + 1 lone pair on Xe).
3. Polarity: Xe-O bonds are polar (electronegativity difference: O > Xe). The trigonal pyramidal shape means bond dipoles do not cancel, resulting in a net dipole moment.

Answer:

The XeO₃ molecule is polar. Its trigonal pyramidal geometry (from Lewis structure with 1 lone pair on Xe) leads to unbalanced bond dipoles, creating a net dipole moment.
