Previously, much has been learned about the periodic table and what it tells about elements. Each listing in the table contains information about the number of protons (Atomic Number), its mass (Atomic Mass), and other information can be derived, such as number of protons and electrons.

In any given chemical reaction, the equation that describes it is made up of numbers and symbols that represent the molecules that are combining. Any molecule is represented by the atomic symbols and subscripts telling how many of each type of atom make up a single molecule.

The action of balancing chemical equations primarily sets out to find the ratios of compounds that result in there being the same number of atoms in the product as there were in the reactants. This is the most fundamental concept that must be understood. It is so important, it bears being repeated and emphasized.

Chemical equations are symbolic representations of how chemicals interact with each other—how they react. The basis of the chemical equation is the chemical notation for molecules of the elements and compounds.
This time, the left side has 4 bacons, 4 pancakes, 2 eggs, and one piece of toast. The right side has to end up with exactly that combination, but since the bacon was plated with the eggs and toast, the pancakes all ended up left over on two plates. The components of the breakfasts are switched around and re-organized so that the new plates are composed of the same things, but in different order.
