About Tungsten
Tungsten is a chemical element with the symbol W and atomic number 74, meaning every atom has 74 protons in its nucleus. It is classed as Transition metal and is a solid at room temperature. Its atomic mass is about 183.84 atomic mass units (u).
On the periodic table, Tungsten sits in group 6, period 6, which determines how many electron shells it has and how it tends to react with other elements.
Uses of Tungsten
In daily life and industry, Tungsten is used for Lamp filaments. These uses are closely tied to the typical properties of elements in the Transition metal category.
Electron Structure of Tungsten
Using a simplified electron shell model (at most 2 electrons in the first shell, 8 in the second, 18 in the third, and so on), Tungsten has 5 electron shells, with an approximate arrangement of 2, 8, 18, 32, 14 electrons from the innermost shell to the outermost. This is a simplified learning model, not the full electron configuration that accounts for the s, p, d and f subshells.
