Select the correct electron configuration for Cu(z=29)
Correct answer: B. [Ar]4S13d10
- A. [Ar]4S23d9
- B. [Ar]4S13d10
- C. [Ar]4S24p63d3
- D. [Ar]4S14d9
Explanation
The correct electron configuration for copper (Cu) with atomic number 29 is:b. [Ar] 4s13d10The electron configuration represents the distribution of electrons in the atomic orbitals of an atom.The electron configuration for copper (Cu) can be determined by filling the orbitals in the order of increasing energy, following the Aufbau principle.The electron configuration of copper is [Ar] 4s13d10. This means that copper has a filled 4s subshell (2 electrons) and a filled 3d subshell (10 electrons).

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
