well good question!!!Thanks for asking it.
Difference between Cu and Cu²⁺:
---> Cu is a neutral atom where number of protons and electrons are equal.
Cu- Atomic number - 29
Number of protons=29
Number of electrons =29
Electronic configuration: 1s2 2s2 2p6 3s2 3p6 4s1 3d10
----> Cu2+ is a cation formed by lossing 2 electrons.
Cu²⁺ : Number of protons : 29
number of electrons : 27
As proton number is more, nuclear Charge for Cu²⁺ will be more and atomic size of Cu²⁺ decreases, Ionization potential is more.So atomic radius of Cu atom is more than Cu2+ ion.
