Tungsten has the highest melting point of all elements at 3,422 C. It is used in light bulb filaments, cutting tools, and military applications.

About Tungsten

No element withstands heat like tungsten (W): with the highest melting point of any element, 3,422 degrees Celsius, it remains solid where other metals vaporize. Element 74 occupies group 6 of period 6 in the d-block, with an atomic mass of 183.84, the electron configuration [Xe] 4f¹⁴ 5d⁴ 6s², and a Pauling electronegativity of 2.36. This refractory nature made tungsten the classic material for incandescent light-bulb filaments, and its hardness underlies tungsten-carbide cutting tools and drill bits. Dense and strong, the metal also serves in armaments and high-temperature furnace components. It is solid at standard conditions.
