2019-08-03 · W Uses Made into filaments for vacuum tubes and electric lights. Also as contact points in cars. Combined with calcium or magnesium it makes phosphors. Tungsten carbide is extremely hard and is used for making cutting tools and abrasives. Atomic Number 74 Learn more about the atomic number. Description Hard, steel-gray to white metal.

The electron configuration tool helps students understand how to place the electrons in energy levels and sublevels. This is a picture of a completed "electron configuration tool" Also as I explain the Aufbau Principle I have them watch a video to give them a visual of how electrons fill energy levels and orbitals.

Atomic Number (Z): 74. Tungsten (W) ::: example of: Elements. A set of atoms with a specific number This is not much of an abbreviation. However, consider the abbreviated electron configuration for W, which has 74 electrons: W: [Xe]6s 2 4f 14 5d 4. This is a significant simplification over an explicit listing of all 74 electrons. So for larger elements, the abbreviated electron configuration can be a very useful shorthand.

The total electron configuration is thus Nb [Kr]4d 3 5s 2 (Note that the principal quantum number of the d subshell is 4 ― one less than the number of the period. Also, if you look at the table of electron configurations, it should be noted that Nb is an exception to the typical orbital filling rules) b) A similar procedure is followed for Pr, element number 59.
