How can I write the formula for zinc chloride?

Answer 1

The formula for zinc chloride is #ZnCl_2#. This represents a ratio of one zinc ion #Zn^(2+)# , to two chloride ions Cl−. This is an ionic compound made up of positive and negative ions. The ions are held together by strong electrostatic forces called ionic bonds. Overall ionic compounds have no charge because the charges cancel each other out, so the charges on the ions are not shown in the formula.
