29 protons and 27 electrons.
29 protons and 27electrons are present in Cu2+ ion.
The chemical symbol is Cu2+.
+2 is the charge represented Cu2+
Copper can have a +2 oxidation state because it can lose two electrons from its outermost shell to achieve a stable electron configuration. This results in the formation of Cu2+ ions with a charge of +2.
The aqueous solution of Cu2+ ions appears blue due to the absorption of certain wavelengths of light. The blue color is a result of the d-d electron transitions within the copper ions, where the electrons absorb energy and transition to higher energy levels, leading to the absorption of specific colors in the visible spectrum, giving the solution its characteristic blue color.
29 protons and 27electrons are present in Cu2+ ion.
Au (gold) has a total of 79 electrons, making it the species with the greatest number of electrons among the options provided.
Cu2+ is a cation as are all positive ions. One way to remember is to think of the "t" in cation as a plus sign.
The stock name for Cu2+ is copper(II).
Cu2+ + I- --> Cu2I The compound created is Copper(I) Iodide
Cu(s) | Cu2+(aq) Au+(aq) | Au(s)
Yes, both Cu+ and Cu2+ violate the octet rule. Copper (Cu) is an exception to the octet rule due to its electron configuration, which allows it to have a partially filled d orbital. This leads to Cu forming compounds where it does not achieve a full octet of electrons.
The chemical symbol is Cu2+.

Cu2+ + O2- + H+ + Cl- = Cu2+ + 2 Cl- + H2O
Cu2 is more active than Cu in chemical reactions because Cu2 has a higher oxidation state, meaning it has more electrons available for bonding and reacting with other substances. This makes Cu2 more likely to participate in reactions and form compounds compared to Cu.
