All you need to do is provide the ionic compound name and hit the calculate button to check the ionic radii, net ionic charge and its formula. You write down problems, solutions and notes to go back. This is to show that the subscript applies to the entire polyatomic ion. Ionic Formula Calculator gives the formula of an ionic compound and net ionic charge details quickly. Chemistry Calculator - Symbolab Chemistry Calculator Calculate chemical reactions and chemical properties step-by-step Chemical Reactions Chemical Properties full pad Examples Related Symbolab blog posts My Notebook, the Symbolab way Math notebooks have been around for hundreds of years. If more than one of a particular polyatomic ion is needed to balance the charge, the entire formula for the polyatomic ion must be enclosed in parentheses, and the numerical subscript is placed outside the parentheses. If you use the criss-cross method and end up. Use the crisscross method to check your work. See if the charges are balanced (if they are youre done) Add subscripts (if necessary) so the charge for the entire compound is zero. The rule for constructing formulas for ionic compounds containing polyatomic ions is the same as for formulas containing monatomic (single-atom) ions: the positive and negative charges must balance. Find the name and charge of the polyatomic ion from the list of polyatomic ions.
