The element tungsten (symbol W, atomic number 74) has the electron configuration. 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d4. and the abbreviated noble gas form Electron Configuration Number of Neutrons Melting Point Symbol: W Atomic Number: 74 Atomic Mass: 183.84 amu Melting Point: 3410.0 °C (3683.15 K, 6170.0 °F) Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a new element in 1781 and first isolated as a metal in 1783. So, we start by writing the first part of tungsten's electron configuration which is [Xe] Next, we have 74-54=20 more electrons to fill.

It was identified as a new element in 1781 and first isolated as a metal in 1783. So, we start by writing the first part of tungsten's electron configuration which is [Xe] Next, we have 74-54=20 more electrons to fill. We know that xenon's full electron configuration is 1s^2\2s^2\2p^6\3s^2\3p^6\3d^10\4s^2\4p^6\4d^10\5s^2\5p^6 From this picture, we see that the next shell we choose to fill will be the 6s orbital.
