Very small numbers can also be expressed using scientific notation. The mass of an electron in decimal notation is 0.000000000000000000000000000911 grams. In scientific notation, the mass is expressed as 9.11 × 10 -28 g. Notice that the value of the exponent is chosen so that the coefficient is between 1 and 10.
