The element having [Ar]$3d^{10}4s^1$ electronic configuration is
The element having [Ar]$3d^{10}4s^1$ electronic configuration is
Show Hint
When analyzing electronic configurations, remember that transition elements may have partially filled 3d subshells and are often confused with each other due to their similar configurations.

- Cu
- Zn
- Cr
- Mn
Show Solution
The Correct Option is A
Solution and Explanation
The electronic configuration [Ar]$3d^{10}4s^1$ identifies Copper (Cu), with atomic number 29.
In this arrangement, the 3d subshell is full, and the 4s orbital contains a single electron.
This configuration differs from those of Zn, Cr, and Mn. Zn exhibits a full 4s subshell and an incomplete 3d subshell, whereas Cr and Mn possess distinct electronic configurations.
In this arrangement, the 3d subshell is full, and the 4s orbital contains a single electron.
This configuration differs from those of Zn, Cr, and Mn. Zn exhibits a full 4s subshell and an incomplete 3d subshell, whereas Cr and Mn possess distinct electronic configurations.
