Chemical properties description:
Zinc is a bluish-white metal.
A density of 7.14 g / cc, a melting point of 419.5 ℃.
At room temperature, brittle; 100 ~ 150 ℃, become softened; exceed 200 ℃, they become brittle.
In nature, the multi-state presence sulfide.
Zinc chemically is active.
In the air of normal temperature, the surface will form a layer of zinc carbonate film. It can prevent further oxidation.
