Cadmium has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10, commonly written in the shorthand as [Kr] 5s2 4d10. For students who have not learnt spdf notation, the configuration is normally written as 2, 8, 18, 18, 2. It has two valence electrons.
The ion would have 8 instead of 10 as the last number.
The condensed electron configuration for copper is Ar 3d10 4s1.
The condensed electron configuration for polonium is [Xe] 6s2 4f14 5d10 6p4
The pseudo noble gas electron configuration for cadmium is [Kr] 4d^10 5s^2. Cadmium forms a 2+ cation to achieve a pseudo noble gas electron configuration, where it loses its two 5s electrons and has the electron configuration of [Kr] 4d^10.
The condensed ground state electron configuration for Barium is [Xe] 6s^2. This indicates that Barium has a full inner electron shell (represented by the noble gas configuration of Xenon) and two electrons in the outermost 6s orbital.
The condensed version (which you want to use for cesium!) is [Xe]6s1 It means cesium has all the electrons in the same places that xenon has, plus one valence electron way out in the 6th level.
The condensed electron configuration for copper is Ar 3d10 4s1.
The electron configuration of mendelevium is [Rn]5f13.7s2.
