What is the charge of a copper atom?

So, the number of protons in copper atom is 29. The protons are present in nucleus of an atom and the charge on proton is +1. Therefore, the charge on nucleus of a copper atom is +29.

Regarding this, what is the charge of copper?

Copper (I) ions have a 1+ charge. This happens when copper atoms lose one electron. Its formula is Cu+ . Copper (II) ions have a 2+ charge.

Also Know, is Copper positive or negative charge? We say that copper is the positive pole and zinc is the negative one, but in reality, the transition of electrons will happen against electrostatic forces, not following them: the positive electrode, copper, will become negatively charged from the extra electrons, at the expense of the negative electrode, zinc which

Beside above, what is the charge of a copper atom if it gains electrons?

If an atom loses electrons it forms a positive ion and if it gains electrons it forms a negative ion. If a copper ion has a charge of +2 it means that it lost two electrons and now has two more protons than electrons.

Why does CU have a 2 charge?

Because the charge field density of the copper atom's electron cloud moves a 4s into 3d. In zinc it'll add a second electron to 4s. Thus, copper certainly does have 2 valence electrons it can lose, giving it an oxidized state of 2+.
