Write the complete ground-state electron configuration of copper.
Understand the Problem
The question is asking for the electron configuration of copper, which involves identifying the arrangement of electrons in the atom at its ground state. Copper has atomic number 29, and its electron configuration can be derived from its position in the periodic table.
Answer
[Ar] 4s¹ 3d¹⁰
The final answer is [Ar] 4s¹ 3d¹⁰
Answer for screen readers
The final answer is [Ar] 4s¹ 3d¹⁰
More Information
The ground-state electron configuration of copper is an exception to the typical order due to increased stability when the d-subshell is fully filled.
Tips
A common mistake is to write [Ar] 4s² 3d⁹, which does not reflect the stability gained by having a filled 3d subshell.
