WebWhen a stable atom gains or loses an electron, it becomes an ion. For example, when chlorine takes an electron from sodium, and sodium gives that electron to chlorine, they become ions and form NaCl. Sodum is a cation (lost an electron and became positive) and chlorine is an anion (gained an electron and becomes negative) in this situation. WebApr 13, 2024 · A phenomenon of supramolecular solvent formation in a micellar solution of alkyl polyglucoside in the presence of primary amine is presented for the first time.
