Question

List of positive and negative radicals in chemistry?

Answer 1

Radicals:

• A radical is known as an atom, molecule, or ion which has an unpaired valence electron in it, which makes radicals chemically very reactive.
• Therefore, a radical ion is a kind of free radical that carries a charge which are two types of radical ions. i.e Ions of positive radicals and Ions of negative radicals.

Positive radicals:

• The atoms acquire a positive charge, when it loses an electron, and are called positive radicals or positive ions.
• positive radical ions are also called radical cations.
• List of Positive radicals: Sodium ( $\mathrm{Na}⁺$) , Hydrogen ( $\mathrm{H}⁺$), Potassium ( $\mathrm{K}⁺$), Lithium ($\mathrm{Li}⁺$), Ammonium ( $\mathrm{NH}₄⁺$).

Negative radicals:

• The atoms acquire a negative charge , when it gains an electron, and are called negative radicals or negative ions.
• Negative radical ions are sometimes called radical anions as well.
• List of Negative radicals:Flouride ( $\mathrm{F}⁻$),Chloride ( $\mathrm{Cl}⁻$),Bromide ( $\mathrm{Br}⁻$),Iodide ($\mathrm{I}⁻$),Sulfate ( $\mathrm{SO}₄²⁻$)

Hence, the above mentioned are the list of positive and negative radicals in chemistry.
