Tungsten has an atomic number of 74. Thus, there are 74 protons/electrons in the nucleus of a Tungsten atom. With an atomic mass of 183.84, tungsten... Learn more about this topic: Tungsten | Definition, Uses & Facts from Chapter 28/ Lesson 32 ...
However, designing materials with strong SOC in realistic materials has been quite straightforward because it simply links to the atomic mass of the constituent elements. Therefore, the candidates for spin-orbit active materials have mostly been limited to solids with heavy elements such as Bi, Sb,...
