What is the formula for the ionic compound composed of the calcium ion and the phosphate ion?
Well, the name will be simple, as by ionic bonding rules, we first write down the name of the cation, in this case calcium, and then the name of the anion, which in this case is phosphate.
The name is thus: calcium phosphate
Now, we need to criss-cross to get the chemical formula. Calcium usually exists in its
To criss-cross, we bring down the
