Question

what is anion and cation​

Answer 1

Explanation:

Anion vs. Cation. Ions result from atoms or molecules that have gained or lost one or more valence electrons, giving them a positive or negative charge. Those with a negative charge are called anions and those with a positive charge are called cations.

Cations and anions are both ions. The difference between a cation and an anion is the net electrical charge of the ion. Ions are atoms or molecules which have gained or lost one or more valence electrons giving the ion a net positive or negative charge.

examples

In chemistry, Anions are negatively charged and Cations are the opposite positively charged.The examples of anions are NO3- or Cl- and Examples of Cations: Na+, Mg2+, Al3+, NH4+ etc.They were are formed when a metal loses electrons and a nonmetal gains those electrons.

Answer 2

HEY MATE HERE IS YOUR ANSWER>>>

ANION>>

A negatively charged ion, i.e. one that would be attracted to the anode in electrolysis.

EXAMPLE >>

$OH^{-}$

CATION >>

A POSITIVE charged ion, i.e. one that would be attracted to the cathode  in electrolysis.

EXAMPLE >>

$H^{+}$
