(Zinc) is a chemical element with chemical symbol Zn and atomic number 30. It is a light gray transition metal. Zinc is the fourth "common" metal, second only to iron, aluminum and copper. However, the most abundant elements in the earth's crust are oxygen, silicon, aluminum, iron, calcium, sodium, potassium and magnesium. In the human body, it belongs to trace elements. The appearance is silvery white, which plays an indelible role in modern industrial battery manufacturing and is a very important metal.

Zinc is hard and brittle at room temperature, but it becomes tough at 100 to 150℃ [1] When the temperature exceeds 2 10℃, zinc becomes brittle again, which can be crushed by knocking. [3] The conductivity of zinc is in the middle. Among all metals, its melting point (420°C) and boiling point (900°C) are relatively low. [4] Except for mercury and cadmium, its melting point is the lowest among all transition metals.

Zinc can be burned in air to produce zinc oxide;

2 Zn + O？ → 2 Zinc oxide

Zinc+X2 → Zinc X2(X=F2, Cl2, Br2, I2)

Zinc+sulfur → zinc sulfide

Zinc+H2O(g)→ zinc oxide+H2
