a cuprous ion has 28 electrons.
28
The ionic bond between cuprous (Cu+) and oxide (O2-) ions involves the transfer of electrons from the cuprous ion to the oxide ion to form an electrostatic attraction between the positively charged copper ion and the negatively charged oxygen ion. This results in the formation of cuprous oxide (Cu2O).
The charge on cuprous ion is +2. It is written as Cu2+.
The formula for cuprous hydroxide is CuOH. It is composed of one copper (Cu) ion and one hydroxide (OH) ion.

There are 18 electrons in a chloride ion.
The ion Fr+ has 86 electrons.
Cu+ named Cu(I) ion, cuprous ... (in salt names, eg. cuprous oxide, Cu2O)
The H+ ion has no electrons.
A potassium ion (K+) has 18 electrons. Potassium has 19 electrons in its neutral state, but when it loses one electron to become an ion, it has 18 electrons.
18 electrons
An Mg2+ ion has lost two electrons, resulting in a total of 10 electrons. Magnesium normally has 12 electrons but when it forms a 2+ ion, it loses two electrons.
