By the elements they create.


When stars near the end of their life, the fusion that has been combining hydrogen atoms to create helium atoms starts creating ever heavier elements.

As a star enters its later stages, a combination of rising heat and gravity start creating elements such as lithium, carbon, and oxygen. Our star is only large enough to create oxygen at periodic number 8.

The extremely large stars which go through a super nova stage, however, will create every element in the natural periodic table. When you consider the density of elements such as silver, gold, lead, and platinum, it takes an extreme amount of heat and gravity to create the heaviest of elements. Any time you touch a piece of silver or gold, remember, those elements only came into existence because a star went through a super nova stage.
