Differentiate between the terms - 'Ion' & 'radical' with suitable examples.
| Ion | Radical |
|---|---|
| An ion is any atom or a group of atoms carrying a positive or negative charge due to loss or gain of electrons. | A radical is an atom or a group of atoms of the same or of different elements that behaves as a single unit with a positive or a negative charge. |
| Positively charged ions are called cations. For example, Sodium [Na1+] | Positively charged radicals are called basic radicals. For example, Ammonium [NH41+] |
| Negatively charged ions are called anions. For example, Chloride [Cl1-]. | Negatively charged radicals are called acidic radicals. For example, Bicarbonate [HCO31-] |
