Web4.1 Positive ions (cations) form by metals losing valence electrons 4.1 Negative ions (anions) form by non-metals gaining electrons 4.1 The number of electrons lost or gained is determined by the electron configuration of the atom 4.1 The ionic bond is due to electrostatic attraction between oppositely charged ions WebThese anionic metal complexes are separated by anion exchange. The Thermo Scientific™ Dionex™ IonPac™ CS5A column has both cation and anion exchange capacity, allowing metals to be separated as cations or anions on a single column. This is called a mixed mode separation. Detection Most hydrated and weakly complexed metals will
