Question

what is anions write its type​

Answer 1

$\huge \mathfrak \green{answer}$

Anions are atoms or radicals (groups of atoms), that have gained electrons. Since they now have more electrons than protons, anions have a negative charge.

Anions are one of the two types of ions. The other type is called a Cation, having a positive charge.

Answer 2

An anion is an ionic species having a negative charge. The chemical species may be a single atom or a group of atoms. An anion is attracted to the anode in electrolysis. Anions are typically larger than cations (positively charged ions) because they have extra electrons around them.
