Discovery Zinc was discovered by Andreas Marggraf at 1746 in Germany. Origin of name: from the German word "zink".

Metal Zinc is a “transition metal” As with all metals, the transition elements are both ductile and malleable, and conduct electricity and heat.

Solid, liquid, gas Zinc is a solid at room temperature

group Group in periodic table: 12 Group name: (none) Period in periodic table: 4 Block in periodic table: d-block

Isotopes Zinc isotopes are used extensively in both industrial and medical applications. It also reduces the release of (stable) Co-59 into the cooling water by forming a thin spinel layer on the Co containing steel surfaces.

Electron configuration Electron Configuration: 1s 2, 2s 2 2p 6, 3s 2 3p 6, 4s 2 3d 10 Ionization energy Ionization energy number /906.4

Transition metal Zinc cannot form an ion with an incomplete d sub–shell and is therefore not a true transition element. Zinc's chemistry is determined solely by the formation of compounds in its +2 oxidation state, but it does form many complexes, though not as many as other transition metals.

Atomic radius Atomic Radius: 133 pm Zinc, Electronegativity: 1.65

Zinc Facts The Element Zinc is defined as a bluish-white, lustrous metallic element that is brittle at room temperature but malleable with heating. Zinc is the fourth most common metal in use.
