Question 14

For each Atom write the number of electrons it must gain or lose to have eight valance electrons. Then calculate the charge of the ion that would form

Answer 14

Calcium, CA positive 2
Phosphorus, P negative 3
Bromine, BR -1
Sulfur, S -2

Question 15

Using your knowledge of valance electrons, explain the main reason so many different molecules are made from carbon atoms

Answer 15

Carbon forms many Bonds (4) because valance shell is half full
