Draw the complete ground$-$state electron configuration $($with electron spin$)$ of the following elements:

a$)$ Potassium

b$)$ Aluminum

c$)$ Iodine

Considered the following molecules: Draw the valence electron configuration of each atom $($including their spin direction$)$ and circle each pair of electrons that make a bond within the molecule. Determine the hybridization state for each carbon atom. Then draw the Lewis Structure and count how many bonds are sigma or pi bonds

a$)H_{2}CO$

b$)C_2{F}_2$

Convert the following structures into skeletal drawings:
