What is the electron configuration of the Cu+ ion?
[Ar]4s03d10 |
[Ar]4s23d9 |
[Ar]4s13d9 |
[Ar]4s23d8 |
Interpretation:
To find out the electronic configuration of Cu+ ions.
Concept introduction:
The distribution of electrons among the various orbitals in the atom is said to be the electronic configuration which is done by following three rules:
- Aufbau Principle
- Pauli exclusion principle
- Hund's rule
For example: The configuration is written as
Correct answer: Option (a)
Explanation of Solution
Reason for correct answer: Argon is a noble gas that falls before copper in periodic table and it is represented in square bracket [
Due to half-filled and completely filled orbitals the compound is stable, so the correct configuration of copper would be
Thus, option (a)

- The solid anhydrous solid CoCl2 is blue in color. Because it readily absorbs water from the air, it is used as a humidity indicator to monitor if equipment (such as a cell phone) has been exposed to excessive levels of moisture.
