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)
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.
