What is the charge of sulfur in S^2-?

Back

The charge of sulfur in S^2- is -2.

Front

How do you determine the correct ratio of ions in an ionic compound?

Back

The correct ratio is determined by balancing the total positive and negative charges of the ions.

Front

What is the significance of prefixes in molecular compounds?

Back

Prefixes indicate the number of atoms of each element in a molecular compound, such as 'di-' for two and 'penta-' for five.
