Electron Configuration Of Potassium And Calcium. It is the eponym of the lanthanide series, a group of 15 similar elements. Potassium electron configuration notation the configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom.
The calcium ion (ca 2+), however, has two electrons less. Potassium and calcium appear in the periodic table before the transition metals, and have electron configurations [ar] 4s 1 and [ar] 4s 2 respectively, i.e. Potassium (k) is an alkali metal found in the first column (group i) and in the fourth row (period 4) of the periodic table.
Californium [rn]7s 2 5f 10:
Thus, potassium has an electron configuration of [ar]4s 1. The electron configuration of the chemical element describes the ground state, i.e. Platinum [xe]6s 1 4f 14 5d 9: Scandium [ar]3d 1 4s 2:
