Question

What do you mean by anion and cation

Answer 1

Explanation:

A cation is a positively charged ion, with fewer electrons than protons, while an anion is negatively charged, with more electrons than protons. Because of their opposite electric charges, cations and anions attract each other and readily form ionic compounds.

Answer 2

Answer:

Cations are positively charged ions. They've lost one or more electrons, but they haven't lost any protons. They thus have a net positive charge. Usually these are metal ions. Good examples that are common:

Sodium, Na+

Potassium, K+

Magnesium, Mg2+

Calcium, Ca2+

Aluminium, Al3+

Iron (II), a.k.a Ferrous, Fe2+

Iron (III), a.k.a Ferric, Fe3+

Hydrogen, H+

On the other hand, Anions are negatively charged ions, meaning that they've accepted one or more additional electrons. Once again, the number of protons remain the same, so there's a net Negative charge. Some of them can get quite big, consisting of more than one atom. Below are some common Anions you might encounter:

Chloride, Cl-

Bromide, Br-

Iodide, I-

Sulfate, SO_3^2-

Nitrate, NO_3^2-

Hydroxide, OH-

Hydride, H-
