The electronic configuration of potassium, K, is [Ar]4s^1. When potassium loses one electron to become a K+ ion, the electronic configuration changes to that of argon [Ar].
The electronic configuration of potassium (K) is 1s2 2s2 2p6 3s2 3p6 4s1.

what is the electronic configuration of the atomC6
The electronic configuration of tin is: [Kr]D10.5s2.5p2.
The element that forms a 2+ ion with the same electronic configuration as Ar is Calcium (Ca). When Calcium loses two electrons, it attains the same electronic configuration as argon by having a full outer shell of electrons.
