Sometimes a specific isotope is prepared in order to gather its decay product. Einsteinium is extremely difficult to produce. Rarely found in its pure form in nature, mercury is typically obtained from the mineral cinnabar. It's also used to make dyes, halogen lights and photographic film. This table is available in , , or as a. The third most abundant gas in the air we breathe, argon is colorless and odorless.
