Zinc was discovered by Andreas Marggraf in 1746 even though European researchers already discovered the element without knowing it. Marggraf used detail in his report so they gave him the credit for discovering the element. Marggraf discovered zinc by heating carbon and calamine. Zinc is a bluish-white color. Zinc’s electron configuration is Ar 3d104s2. Zinc is a part of ZnSO4 and ZnO. Zinc is a transition metal which means it has 2 valence electrons and 4 valence shells. A physical and chemical property of zinc is ductility and malleability. Zinc has an atomic number of 30 and an atomic mass of 65.38. Its melting point is 787 degrees fahrenheit and its boiling point is 1,665 degrees fahrenheit. Zinc is found in mineral deposits.People use zinc for all kinds of reasons. The metal, zinc, is used as coating for steel and iron to they don’t rust which is called galvanization. Half of the 12 million tons produced goes to galvanization. 97.5 percent of pennies are zinc.
