The copper ion has a charge (oxidation state) of 2+. The chloride ions all have a charge of 1-, so the overall charge on the complex ion is 2+ + 4 (1-) = 2-
WebHere, we can see how an electron is transferred from sodium to chlorine in order to form the ions Na ^+ + and Cl ^- −. Once these ions are formed, there is a strong electrostatic attraction between them, which leads to the formation of an ionic bond. The ammonium cation is a positively-charged polyatomic ion with the chemical formula NH+4 or [NH4] . It is formed by the protonation of ammonia (NH3). Ammonium is also a general name for positively charged or protonated substituted amines and quaternary ammonium cations ([NR4] ), where one or more hydrogen atoms are replaced by organic groups (indicated by R).
