74 W 텅스텐 183.84 u

텅스텐 개요

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.
