The electron configuration of Cu2+ is [Ar]3d94s0.
There is 1 unpaired electron in Copper (Cu)
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.
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.
Cu(I), cuprous, Cu+.
the condensed electron configuration for Lu is [Xe] 6s^2 4f^14 5d^1
There is 1 unpaired electron in Copper (Cu)
The electron configuration of a Copper(II)ion is [Ar]4s0 3d9.
1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 Rb+1 or Kr
Cu+3 reported formally in 2007. Cu 1 e's in 4S and 10 e's in 3D Cu+3 0 e's in 4S and 8 e's in 3D LFSE suggets the existence of Cu+3.
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.
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.
Cu(I), cuprous, Cu+.
"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.
Sodium and lithium ions have a +1 charge because they lose one electron to achieve a stable electron configuration. Both elements have one electron in their outermost shell, so it is energetically favorable for them to lose this electron to attain a stable, noble gas configuration.
