a$)$ Draw the best Lewis structure$($s$)$ for $[$TeS$3]2-.$ Show all electrons explicitly. If an atom has a

formal charge, this should also be explicitly indicated. State the total number of valence electrons

in the anion.

b$)$ What are the formal oxidation states of Te and S in $[$TeS $3]2-?$

c$)$ Predict the structure of $[$TeS $3]2-$ using VSEPR rules. Make a clear, geometrically correct drawing

of the structure.
