Cations are ions that are positively charged. Anions are ions that are negatively charged. Ions are charged atoms or molecules. If a balanced atom loses one or more electrons, it will become a ...

A cation refers to an atom or a group of atoms that bear one or multiple positive electric charges. An anion refers to an atom or a group of atoms that bear one or multiple negative electric charges.

and in the center of the cube (one more cation). Thus we have four anions (FCC) and four cations, which corresponds with the stoichiometry of the salt (1:1). occupying the tetrahedral holes. Remember ...

Recently, a team of scientists has constructed a poly (p-terphenyl isatin) anion exchange membrane with quaternary ammonium and piperidine cations synergistic functionalization that provides ...
