S 2- the ide suffix indicates that it is a simple. The subscripts in this formula are not the smallest-possible whole numbers as each can be divided by 2 to yield the empirical formula NaCO 2. The formula for an ionic compound must contain the same number of positive and negative charges.
So that the charges are balanced and it is neutral overall.
So that the charges are balanced and it is neutral overall. Ionic compounds typically have high melting and boiling points and are hard and brittle. Give the molecular formula of aluminum sulfide. Al 3 if you forget the charge of the aluminum ion look up the position of Al in the periodic chart.
