The electron configuration of Cu2+ is [Ar]3d94s0.
There is 1 unpaired electron in Copper (Cu)
The ground state electron configuration for copper (Cu), which has an atomic number of 29, is [Ar] 3d^10 4s^1. This configuration reflects the filling of the 3d subshell with ten electrons and one electron in the 4s subshell. The stability of the fully filled 3d subshell contributes to the unique electron arrangement of copper compared to its neighboring elements.
Fr is in the 1st period. It removes an electron to get noble gas configuration. Fr+ does not have valence electrons.Francium has 1 electron in its outermost energy level. It donates its outermost electron to stabilize its electron configuration. Francium(I) has no valence electrons.
Cu(I), cuprous, Cu+.
The noble gas configuration of copper (Cu) is [Ar] 3d^10 4s^1. The noble gas that would be listed is argon (Ar), which has an electron configuration of 1s^2 2s^2 2p^6 3s^2 3p^6.

The configuration of the lithium ion (Li⁺) is 1s². In its neutral state, lithium has the electron configuration of 1s² 2s¹, but when it loses one electron to become Li⁺, it loses the 2s electron, leaving only the 1s electrons.
Fr is in the 1st period. It removes an electron to get noble gas configuration. Fr+ does not have valence electrons.Francium has 1 electron in its outermost energy level. It donates its outermost electron to stabilize its electron configuration. Francium(I) has no valence electrons.
Cu(I), cuprous, Cu+.
The noble gas configuration of copper (Cu) is [Ar] 3d^10 4s^1. The noble gas that would be listed is argon (Ar), which has an electron configuration of 1s^2 2s^2 2p^6 3s^2 3p^6.
"Cuprous" is an archaic term for what today is called copper (I), Cu+1.
Fluorine's electron configuration is 1s2 2s2 2p5, and since fluoride is just fluorine with an extra electron, or F-1, its electron configuration is 1s2 2s2 2p6.
The electron configuration of curium is [Rn]5f7.6d1.7s2.
