e.g. Na + SO4 2- -> Na2SO4
The chemical formula for the ionic compound containing calcium and fluorine is CaF2.
To write the chemical formula of a compound with polyatomic ions, first determine the charge of each ion. Then, balance the charges by crisscrossing the numerical values of the charges to determine the subscripts of each ion in the formula. Finally, write the formula with the proper subscripts for each ion to balance the charges.
To write the formula for a ternary ionic compound, determine the charges of the ions involved. The charge of the cation becomes the subscript for the anion, and vice versa. Balance the charges to ensure overall neutrality in the compound. Remember to use parentheses when needed for polyatomic ions.
Molecular formula for aluminium iodide : All3
You use the criss cross method to swith the charge of the element with the charge of the whole ion If the charge of the element is more than one then put the ion in parenthesis and then put the charge outside

The formula for the compound of barium and fluoride is BaF2.
To write a formula for an insoluble compound, you need to determine the charges of the ions involved and balance them to create a neutral compound. This involves using the crisscross method to determine the subscripts for each ion in the formula.
The formula for the binary compound of calcium and oxygen is CaO. This compound is known as calcium oxide.
The formula for manganese(II) iodate is Mn(IO3)2. The manganese ion is present in its +2 oxidation state, while iodate is a polyatomic ion with the formula IO3-.
It is written as Na2CO3. It is a base compound.
The formula for lithium oxide is Li2O.
