tungsten is a metal element with the element symbol W. It has high hardness, high melting point, and is not corroded by air at room temperature; it is mainly used to manufacture filaments, high-speed cutting alloy steels, super-hard molds, and also used in optical instruments and chemical ...
Isotopes are two or more forms of an element. Isotopes differ from each other according to their mass number. The number written to the right of the element's name is the mass number. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element...
Tungsten is located on the periodic table under the symbol “W” with the atomic number of 74 (atomic numbers are based on number of protons an element contains). Tungsten is extremely strong, dense, and hard to melt, making it perfect for use in industrial applications and everyday products...
