Rules for Writing Chemical Formulas for Ionic Compounds 1. Identify the positive ion and the negative ion. 2. Find the chemical symbols for the ions, either in the periodic table or in the

In chemistry, chemical reactions are frequently written as an equation, using chemical symbols. The reactants are displayed on the left side of the equation and the products are shown on the

Instead of writing the element or compound name every time, scientists have symbols for each element, which makes writing about them easier.
