Zinc is a chemical element with the symbol Zn and atomic number 30. It is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table.
The chemical elements can be broadly divided into metals, metalloids, and nonmetals according to their shared physical and chemical properties.All elemental metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metallic elements; and have at least one basic oxide.
Zinc is bluish-white and lustrous, [9] though most common commercial grades of the metal have a dull finish. [10] Zinc is also referred to in nonscientific contexts as spelter. [11] Cadmium is soft, malleable, ductile, and with a bluish-white color. Mercury is a liquid, heavy, silvery-white metal.

Iron can also be oxidized by marine microbes under conditions that are high in iron and low in oxygen. [202] Iron can enter marine systems through adjoining rivers and directly from the atmosphere. Once iron enters the ocean, it can be distributed throughout the water column through ocean mixing and through recycling on the cellular level. [203]
An amorphous metal (also known as metallic glass, glassy metal, or shiny metal) is a solid metallic material, usually an alloy, with disordered atomic-scale structure. Most metals are crystalline in their solid state, which means they have a highly ordered arrangement of atoms .
Hiduminium or R.R. alloys (2% copper, iron, nickel): used in aircraft pistons Hydronalium (up to 12% magnesium, 1% manganese): used in shipbuilding, resists seawater corrosion Italma (3.5% magnesium, 0.3% manganese): formerly used to make coinage of the Italian lira
Terne II used zinc in place of lead for environmental reasons. [5] Today's aesthetic behavior is the main reason and benefit of the tin coating. Tin develops a natural matte grey patina when exposed to the elements. The result of the weathering process depends on the environment and climate conditions present.
