For chemistry students and teachers: The tabular chart on the right is arranged by elements in human body. The first chemical element with the highest percentage is Oxygen and the last one with the lowest percentage is Magnesium. The unit for the elements in the human body is %. Please note that the elements do not show their natural relation towards each other as in the Periodic system. There you can find the metals, semi-conductor(s), non-metal(s), inert noble gas(ses), Halogens, Lanthanoides, Actinoids (rare earth elements) and transition metals.	traces	Copper
