WebThe average 70 kg (150 lb) adult human body contains approximately 7 × 1027 atoms and contains at least detectable traces of 60 chemical elements. [6] About 29 of these elements are thought to play an active positive role in life and health in humans. [7] WebIn general, atoms are most stable, least reactive, when their outermost electron shell is full. Most of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule.
