Question:
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.
