In chemistry the criss-cross method is a way to write the formulas of ionic compounds. The criss-cross method makes it easier to determine the subscripts for each element in an ionic compound.
Using this method the number associated with the charge of the first ion is assigned as the subscript of the second ion. We know that the crisscross method is used to determine the chemical formula. We can write the chemical formula of the ionic compound by the following steps using criss cross method 1We have to write symbols and charges of the anion and cation.
The cation is written first and then anion is written. 2We have to transpose the number of positive charges to become the subscript of the anion and the. As we know that the criss-cross method is the most efficient way to write the correct chemical formula of the molecule.
It is generally used for finding out the formula of a bonding of a metal with a non-metal to form ionic bonds. Signs of the two ions are dropped the ion value is crossed which becomes the subscript of the crossed atoms.
