The shell configuration of potassium is 2,8,8,1.
No - but the potassium ion does

Chromium (24Cr) electron configuration: [Ar] 3d5 4s1 Complete [1s2, 2s2 2p6, 3s2 3p6] 3d5, 4s1
Chromium has a half filled D orbital so is stable.

Ar is Argon and Ar 4s1 is the short form of the electron configuration 1s2 2s2 2s6 3s2 3s6 4s1. It means add 4s1 to the electron configuration of Argon to get the electron configuration of potassium.
Potassium must lose one electron (to have the same configuration as the noble gas argon), and fluorine must gain one electron (to have the same configuration as neon)
The electronic configuration of chromium is 1s2 2s2 2p6 3s2 3p6 3d5 4s1.
The electron configuration for a ground-state potassium atom is 1s22s22p63s23p64s1. The noble gas shorthand configuration is [Ar]4s1.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
