Please someone explain me the SPDF method ......................... all those how many how electrons can be stored by S P D and F shells?????????????????? PLEASE HELP ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
If we think of electron configurations as an electron's "address". The s, p, d, and f tell us the type of house they live in and refer to the shape of the orbital where we find a particular electron.
Each orbital, no matter what the type, can only hold 2 electrons. When we look in any one principal quantum shell (i.e. n=3), we can have multiples of some orbital types. There is only 1 s orbital in each shell, but there are three p orbitals, 5 d-orbitals and 7-f orbitals. We don't have any d orbitals until the n=3 level and no f-orbitals until n=4
The SPDF refers to how the electrons are configured. The S, P, D, and F are orbital names that are short for sharp, principal, diffuse, and fundamental. I actually found you a useful chart you can use that shows the electron capacity of each.
