Nickel

Description




Ni is the chemical symbol of nickel in the VIIIB group of the periodic table and its atomic number is 28. Its density is 8.908 g/cm³. The melting and boiling points of nickel are 1728K (1455 °C, 2651 °F) and 3186 K, (2913 °C, 5275 °F) respectively. Pure nickel is a silvery grey metal. When it is exposed to air, a layer of the basic oxide surface is formed to protect nickel from further oxidation. Therefore, the nickel we see is usually grey white. Nickel is hard, malleable, ductile and can be highly polished
