Properties of tungsten

Answer 1

tungsten is used to make the filament of bulb because of it's properties:

it has a rather high ignition temperature

it glows when an electric current passes through it

it breaks when there is overload of electricity in the circuit, thus, making the circuit

incomplete, so, no electric current passes through it.

tungsten has many strange properties which make it an ideal filament for a bulb

Answer 2

Tungsten, also known as wolfram, is an element with the symbol W and atomic number 74. Tungsten is as known as one of the heaviest materials except gold for the density of tungsten is 19.25  g•cm−3.

Tungsten is a typical element of transition element Group VI and shows oxidation states from +6 to-2 and, particularly in its oxides, forms many non-stoichiometric compounds. There is little aqueous chemistry except that of complex oxy-anions and some complex halides. The hexahalides are molecular but lower halides are polymeric and the lowest halides show extensive W-W bonding (more than Mo). Carbonyl and phosphine derivatives are typical low oxidation state compounds. Complexes are formed, particularly by O-and S-ligands in higher oxidation states and by P-ligands in low oxidation states. Complex cyanides are well established.

Tungsten is a Nonferrous Metal and is also Refractory. It is one of the most important Strategic Metals for IT industrial and military industrial.
