fill out the information below for the polyatomic anion in the formula unit M2SeO3 where M represents an alkali metal.

A. Number of valence electrons

B. Lewis Structure

C. 3D Sketch

D. Electron geometry

E. Molecular geometry

F. Hybridization

G. Overall polarity (nonpolar or polar)

Expert Solution

Answer – We are given the formula M₂SeO₃

A. Number of valence electrons

Total valence electrons = (2*1) + (1*6) + (3*6)

= 26 electrons

B. Lewis Structure

C. 3D Sketch

D. Electron geometry

Central atom has 3 bonding and 1 lone pair, so total 4 pair of bonding, so electronic geometry is tetrahedral.

E. Molecular geometry

Central atom has 3 bonding and 1 lone pair, so molecular geometry is trigonal pyramidal.

F. Hybridization

The hybridization of the M₂SeO₃ around the Se is sp³.

G. Overall polarity (nonpolar or polar)

The overall polarity of this molecule is polar, since there is unsymmetrical and two O one side and one at one side, so this is the polar molecule.
