Give the actual ground-state electron configuration for copper (Cu) using the complete form.?

Express the electron configuration using superscripts where appropriate. For example, the configuration for Li would be entered as 1s^22s^1.

Thank you so much for your help in advance.!!

  • The reason it is incorrect is you must fill the 4s orbital before the 3d Orbital. However, Copper is exempt from fully filling the 4s orbital. so it should look like below with the 3d orbital fully filled, and the 4s orbital with just 1 electron.

    1s^2 2s^2 2p^6 3s^2 3p^6 4s^1 3d^10

  • Cu - 1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^1

  • [Ar]4s^13d^10

  • This answer is incorrect Usama. Thanks for trying though.

    ** I figured it out. For anyone else looking for this question, the 4s^2 should be 4s^1.
