The formula for the ionic compound formed between calcium ions and chloride ions is CaCl2. What does this formula tell you about
the compound?
Each molecule of CaCl2 has one calcium ion and two
chloride ions.
Each calcium ion in the compound has exactly two chloride
ions bonded to it.
Calcium and chloride ions exist in a 1:2 ratio in a crystal of
CaCl2.
All of these are true.
