We’re being asked to determine the electron configuration of Cu.
You can determine the ground-state electron configuration of Copper (Cu) by locating its position in the periodic table.
Ground-state means that the element is in its lowest energy form (not in excited state). Neutral neon means it has no charge, meaning no electrons are removed or added in the atom.
You can see in the above illustration of the periodic table that Pd is in Period 4, Group 10, and d-block.
Cu has an anomalous electron configuration. Write the observed electron configuration of Cu.
Express your answer in complete form in order of increasing orbital energy.
