Answer:
Electronic configuration:
Cu₂₉ = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹ 3d¹⁰
Explanation:
Copper is present in group 11.
Its atomic number is 29.
Electronic configuration:
Cu₂₉ = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹ 3d¹⁰
The noble gas notation is used for the shortest electronic configuration of other periodic table elements.
For example:
The atomic number of Argon is 18, and its electronic configuration is,
Ar₁₈ = 1s² 2s² 2p⁶ 3s² 3p⁶
Abbreviated electronic configuration:
Cu₂₉ = [Ar] 4s¹ 3d¹⁰
Copper can not show +4 oxidation state that's why electronic configuration can not be written for Cu +4. Its oxidation states are +1 and +2. The +1 is rare while +2 is most common oxidation state.
Electronic configuration for Cu⁺:
Cu₂₉ = [Ar] 4s⁰ 3d¹⁰
Electronic configuration for Cu²⁺:
Cu₂₉ = [Ar] 4s⁰ 3d⁹
