The Criss Cross Method is used to find the general formula for ionic compounds. For monatomic ions, you simply take the absolute value of the ionic charge for the positively charge ion and make it the subscript for the negatively charged ion and vice versa. Example: Al +3 and Cl -1 The 3 becomes the subscript for the chloride ion and the 1 becomes understood for aluminum, to form aluminum chloride: AlCl3 Ionic compounds that form from polyatomic ions can also make use of the criss cross method. The only additional step is to include parenthesis around the polyatomic ion if it has a subscript other than one. Example: Mg+2 and OH-1 The 2 becomes the subscript for the hydroxide ion, but a set of parenthesis is needed to indicate 2 of each the O and the H. The 1 becomes the understood subscript for Mg. Magnesium Hydroxide: Mg(OH)2
To write the formula of ammonium carbonate using the criss-cross method, you first write the symbols of the ions (NH4+) and (CO3^2-) side by side. Then, you criss-cross the numerical values from the charges of the ions to give you the formula NH42CO3.
The chemical formula of potassium sulfate using the criss-cross method is K2SO4. This method involves swapping the numerical values of the charges on the ions to determine the subscripts in the compound.
To find the formula for ammonium chloride (NH4Cl) using the criss-cross method, you would cross the charges of the ammonium ion (NH4^+1) and the chloride ion (Cl^-1). The resulting formula will have one ammonium ion and one chloride ion, giving you NH4Cl.
The molecular formula of water is H2O. This means that each water molecule contains two hydrogen atoms and one oxygen atom. The criss cross method is typically used for ionic compounds to determine the ratio of ions in the compound.
The molecular formula of ammonium sulfate is (NH4)2SO4. This is derived using the criss-cross method, which involves crossing the numerical charges of the ions to determine the subscript for each element in the compound.

The formula for magnesium carbonate using the criss-cross method is MgCO3. This is because the charge on magnesium is 2+ and the charge on carbonate is 2-, so when the charges are criss-crossed, the subscripts become 1 for Mg and 1 for CO3, resulting in MgCO3.
When using the criss cross method with a polyatomic ion, simply treat the polyatomic ion as a single unit. Cross the charges of the cation and anion to determine the subscript of the other ion. Ensure to simplify the ratio by reducing to the lowest whole numbers.
