The name of each element (in brown) is accompanied by its chemical symbol (in red), as well as its atomic number Z and its most common (or most stable) mass number A. This simplified version of the Aufbau principle explains the structure of the periodic table of elements, where elements with similar chemical properties are listed in the same column: The chemical properties of an element depend mostly on the valence electrons located in the outermost subshell(s) which are usually the least favored energetically (with the reservations noted below, in the case 2019-10-17 · Colored Periodic Table To Print and Use This periodic table image can be downloaded to print or used as a desktop wallpaper.

From here, tungsten is number 74 on the periodic table, so the closest noble gas to it would be xenon, which is number 54. So, we start by writing the first part of tungsten's electron configuration which is. Next, we have 74 −54 = 20 more electrons to fill. We know that xenon's full electron configuration is 1s22s22p63s23p63d104s24p64d105s25p6.

Tungsten is a chemical element with symbol W and atomic number 74. Classified as a transition metal, Tungsten is a solid at room temperature.

Impure metal is brittle and worked only with difficulty, and Pure tungsten is a lustrous, steel-gray to tin-white metal, which can be Spun, drawn, forged, extruded, and cut with a hacksaw. It is the heaviest, and most refractory (resistant to heat) metal on the earth. Number of Electrons (with no charge): 74; Number of Neutrons (most common/stable nuclide): 110; Number of Protons: 74; Oxidation States: 6,5,4,3,2; Valence Electrons: 5d 4 6s 2 Electron Dot Model.
