Zinc is an essential mineral for human health, important for immune function, white blood cell formation, egg fertilization, cell division and other enzymatic reactions. It is the second-most abundant metal in the body, after iron. Zinc deficiency is evidenced by abnormalities of smell and taste.
It is also crucial to industrial processes.
A German chemist isolated zinc in a lab 1746 and became known as inventor of the process. But it turns out that other European researchers had already done the same.
Ancient people used zinc ores to make brass (an alloy of copper with zinc). Zinc was recognized as a metal in India in 1374.

Zinc is found in zinc oxide used in sunscreens, solar cells and nuclear reactors to prevent corrosion.
Lead is non-ferrous. We accept:
