Ionic compound: Ionic compound consists of cation which is positively charged (+charge) and an anion which is negatively charged (-charge).
Ionic compounds are named by writing the name of the cation first, followed by the anion.
If a metal can form cations with more than one charge, they are named accordingly with the use of roman numerals in parentheses.
Empirical formula: It can be defined as the simplest whole number ratio of different atoms present in the compound.
To find the empirical formula of an ionic compound, first identify the cation and write down its symbol and charge.
Then, identify the anion and write down its symbol and charge.
Finally, combine the two ions so that they form an electrically neutral compound.
