The shell configuration of potassium is 2,8,8,1.
The electron configuration of scandium is: [Ar]3d1.4s2.
In humans
Iron does not have a closed shell configuration because it has incompletely filled d-orbitals in its electron configuration. In the case of iron, the electrons in the 3d orbitals prevent it from achieving a closed shell configuration.

The electron configuration of silicon is 1s2 2s2 2p6 3s2 3p2. You can represent this in shorthand notation by writing [Ne] 3s2 3p2, which indicates that silicon's configuration is the same as neon's configuration followed by the outermost electron sublevels of 3s2 3p2.
