The extra electron would go into a 4s orbital because 4s can hold up to 2 electrons before 3d can be filled.
Copper (Cu) has one 3d electron.
Iron has the electron configuration [Ar]3d64s2.

The extra electron would go into a 4s orbital because 4s can hold up to 2 electrons before 3d can be filled.
The element that contains five electrons in its 3d orbital is manganese (Mn). Manganese has an atomic number of 25, and its electron configuration is [Ar] 4s² 3d⁵. This means it has five electrons in the 3d subshell.
Copper (Cu) has one 3d electron.
Iron has the electron configuration [Ar]3d64s2.
A positive ion ( the one that gives the electron) and a negative ion ( the one that accepts).
The element with the lowest atomic number that contains a half-filled d subshell at its ground state is scandium (atomic number 21). The electron configuration of scandium at ground state is [Ar] 3d^1 4s^2, where the 3d subshell is half-filled with one electron.
The correct electron configuration would be 3d5 as each orbital in the 3d sublevel can hold up to 2 electrons, and we have 5 electrons to place in this sublevel.
