Electron Configuration of Copper

This video tutorial explains how to write the electron configuration for copper, including its ions Cu+ and Cu2+. Copper is an exception to the usual rules, making it important to understand. The video covers the step-by-step process of writing the configuration, highlights the correct configuration due to electron stability in d orbitals, and demonstrates the condensed notation. It also explains how to adjust the configuration for copper ions by removing electrons.

Why is copper considered an exception when writing electron configurations?

• It follows the standard rules without exceptions.

• It is not found on the periodic table.

• It has a unique electron configuration due to its stability.

• It has more protons than electrons.

How many electrons does neutral copper have?

• 31

• 28

• 29

• 30

What is the electron configuration for neutral copper if following the standard rules?

• 1s2 2s2 2p6 3s2 3p6 4s1 3d10

• 1s2 2s2 2p6 3s2 3p6 4s1 3d9

• 1s2 2s2 2p6 3s2 3p6 4s2 3d9

• 1s2 2s2 2p6 3s2 3p6 4s2 3d10

Why is the electron configuration 4s1 3d10 more stable for copper?

• Because half-filled and fully filled d orbitals are more stable.

• Because it uses more energy.

• Because it has fewer electrons.

• Because it is less stable.

What is the condensed electron configuration notation for copper?

• [Ar] 3d10 4s1
