Predicting Chemical Reactions
Learning Objective
I can predict the products of simple chemical reactions using the periodic table.
Key Concepts
When predicting products of chemical reactions, it is important to know the charges of all elements and polyatomic ions.
When predicting products, the inner elements combine with the inner elements, and the outer elements combine with the outer elements.
When writing a chemical formula, the positive element (usually a metal) goes first, followed by the negative element (usually a nonmetal).
