Question:medium
The element having \([Ar]3d^{10}4s^1\) electronic configuration is
The element having \([Ar]3d^{10}4s^1\) electronic configuration is
Show Hint
Copper (Cu) has an electron configuration of \( [Ar] 3d^{10} 4s^1 \), which is an exception to the general electron configuration rule due to stability gained by a filled 3d subshell.
Updated On: Jan 13, 2026
- Cu
- Zn
- Cr
- Mn
Show Solution
The Correct Option is A
Solution and Explanation
The electron configuration \( [Ar] 3d^{10} 4s^1 \), which signifies an atomic number of 29, identifies Copper (Cu).
Step 2: Therefore, option (1) is the correct answer.
Step 2: Therefore, option (1) is the correct answer.
