How many protons and electrons are in 64 29 Cu2 plus ion?
29 protons and 27electrons are present in Cu2+ ion.
What is the chemical symbol for an ion with 29 protons and 27 electrons?
The chemical symbol is Cu2+.
What is the charge on an atom of copper that has lost two electrons and how is this ion represented?
+2 is the charge represented Cu2+
Why copper has 2 plus oxidation state?
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.
Why is the aqueous solution of Cu2 plus blue?
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.
How many protons and electrons are in 64 29 Cu2 plus ion?
29 protons and 27electrons are present in Cu2+ ion.
What species has the greatest number of electrons I- or Cu2 plus or Fe3 plus or Au or Hg?

What is the correct cell notation for the reaction 2Au plus aq plus Cus 2Ausplus Cu2 plus aq?
Cu(s) | Cu2+(aq) Au+(aq) | Au(s)
Do Cu plus and Cu2 plus plus violate the octet rule?
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.
What is the chemical symbol for an ion with 29 protons and 27 electrons?
The chemical symbol is Cu2+.
Calculate the standard emf of a cell that uses the Mg Mg2 plus and Cu Cu2 plus half cell reactions at 25 degrees C?

What is the complete ionic equation for copper II oxide plus hydrochloric acid yield copper II chloride plus water?
Cu2+ + O2- + H+ + Cl- = Cu2+ + 2 Cl- + H2O
Why is Cu2 more active than Cu in chemical reactions?
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.
