What is the ground state of Kr?

The ground state of krypton (Kr), which has an atomic number of 36, is represented by the electron configuration 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶. In this configuration, all electrons are in their lowest energy levels, and Kr is chemically stable and inert due to having a complete outer electron shell. As a noble gas, krypton does not typically form bonds with other elements.
