21 Αυγ 2024 · Zinc, chemical element, a low-melting metal of Group 12 of the periodic table, that is essential to life and is one of the most widely used metals. Zinc is of considerable commercial importance. Learn more about the properties and uses of zinc in this article.
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.
21 Αυγ 2024 · In chemical compounds, zinc exhibits almost exclusively a +2 oxidation state. A few compounds of zinc in the +1 state have been reported, but never any compounds of zinc in the +3 state or higher. Zinc oxide, ZnO, is one of the most important zinc compounds.
30 Ιουν 2023 · Zinc (Zn) is a blue-white metal of moderate strength, hardness and ductility. Zinc is one of the least common elements and is mostly produced through electrolysis of aqueous zinc sulfate. About one third of all metallic zinc is used to manufacture galvanized nails.
Represented in the periodic table as Zn, zinc is a transition metal, grouped with cadmium and mercury. With the middling atomic number 30, it has five stable isotopes of atomic weight from the dominant zinc 64 to zinc 70, plus an extra 25 radioisotopes.
28 Ιουν 2024 · Role in Chemistry: Zinc plays a vital role in various industrial applications, including galvanization to protect iron and steel from rusting. It also forms a variety of compounds, such as zinc oxide and zinc sulfate, used in materials, agriculture, and medicine, making it an important material in a wide range of fields
Chemical Characteristics. Zinc is a reactive metal. The surface of zinc metal is quickly tarnished as it reacts with the carbon dioxide present in the air and forms a layer of zinc carbonate. It is a strong reducing agent [4]. Zinc readily reacts with non-metals, acids and alkalis.
