Verified Answer :

The total number of electrons in a Cu + Ion is 28.

Answer: The number of electrons in Cu^+ ion is 28.

Explanation: Copper has atomic number of 29 which means it has 29 electrons and 29 protons.

Argon is the noble gas with 18 electrons.

\(Cu(29 -[Ar]3d^{10}4s^1\)

When Cu lose one electron it forms \(Cu^+\) as now the number of protons are greater than the number of electrons.

The configuration of \(Cu^+\) becomes \([Ar]3d^{10}\)
