(ˈænˌaɪ ən)

n. 1. a negatively charged ion that is attracted to the anode in electrolysis. 2. any negatively charged ion (opposed to cation). [1825–35; < Greek, neuter of aniṓn, present participle of aniénai to go up] an`i•on′ic (-ˈɒn ɪk) adj. an`i•on′i•cal•ly, adv.

an·i·on

(ăn′ī′ən) An ion that has a negative charge. Hydroxide and chloride ions are anions. Compare cation.

anion

An ion that carries a negative charge, especially one migrating to an anode during electrolysis.

an·i·on (A^-),

(an'ī-on), An ion that carries a negative charge, going therefore to the positively charged anode; in salts, acid radicals are anions.

an·i·on

(A^-) (an'ī-on) An ion that carries a negative charge, going therefore to the positively charged anode; in salts, acid radicals are anions.

anion

A negatively charged ion that is attracted to an anode (positively-charged electrode), in electrolysis. Anions are usually shown as the second group in simple inorganic molecules, thus Cl- is the anion when common salt (NaCl) is dissociated in solution. Na+ is the CATION.

anion

a negatively charged ion that is attracted to the ANODE during electrolysis.

Anion

An ion carrying a negative charge owing to a surplus of electrons. Anions in the body include bicarbonate, chloride, phosphate, sulfate, certain organic acids, and certain protein compounds.Mentioned in: Electrolyte Supplements

(Ā) (an'ī-on) An ion that carries a negative charge, going therefore to the positively charged anode; in salts, acid radicals are anions.
