Do you have to choose coefficients that will balance the equation in balancing an equation

If your goal is to balance the equation, then yes, you have to chose the coefficients.

Which of these elements is not diatomic potassium chlorine iodine or hydrogen

Potassium Chloride is not diatomic. Although chloride is a diatomic molecule (BrINClHOF), the formula for Potassium Chloride is KCl not KCl2. Therefore, it is not diatomic.
