Whole numbers are numbers without fractions or decimals, like 0, 1, 2, 3, and so on. They include zero and all positive integers. We use them to count things and do simple calculations.
When two elements combine and form more than one compound, the masses of one element that react with a fixed mass of the other are in the ratio of small whole numbers. Humphry Davy
