Tungsten

Tungsten is atom number 74 — every Tungsten atom has exactly 74 protons in its center, and that number is what makes it Tungsten and nothing else. Its symbol is W. At room temperature it is a solid.

Tungsten, also known as wolfram, is a chemical element with symbol W and atomic number 74. The word tungsten comes from the Swedish language tung sten, which directly translates to heavy stone. Its name in Swedish is volfram, however, in order to distinguish it from scheelite, which in Swedish is alternatively named tungsten.

Summary from the source dataset, derived from Wikipedia (CC BY-SA 3.0) · original article

Tungsten sits in period 6, group 6 of the d-block. Its 74 electrons fill shells of 2, 8, 18, 32, 12, 2 — written as [Xe] 4f14 5d4 6s2. Its electronegativity is 2.36 on the Pauling scale, and pulling the first electron off takes 770 kJ/mol. The outermost shell holds 2 electrons — the ones that do all the chemistry.
