Ionic comes from ion as you might have guessed. An ion is a charged particle (either positive or negative), and ionic is the adjective meaning charged. An ionic bond is a chemical bond based on electrostatic attraction (the attraction of charges), and we generally associate it with the bonding of metals to non-metals.
An ionic liquid (IL) is a salt in the liquid state. In some contexts, the term has been restricted to salts whose melting point is below some arbitrary temperature, such as 100 Â°C (212 Â°F). While ordinary liquids such as water and gasoline are predominantly made of electrically neutral molecules, ionic liquids are largely made of ions and short-lived ion pairs.
