There are approximately 7 x 1027 atoms in the average human body. This is the estimate for a 70 kg adult human male. Generally, a smaller person would contain fewer atoms; a larger person would contain more atoms. On average, 87% of the atoms in the body are hydrogen or oxygen. Carbon, hydrogen, nitrogen, and oxygen together account for 99% of the atoms in a person. There are 41 chemical elements found in most people. The exact number of atoms of the trace elements varies widely according to age, diet, and environmental factors.

It is widely known that the 50 stars on the flag of the United States represent the states themselves. When the Stars and Stripes was adopted in 1777 there were 13 states (then colonies), thus a 13-star flag, and as each new state was admitted to the union a star was added to the flag.
