what is ionic bond? List some properties????
Answers
Ionic bonding is a type of chemical bond in which valence electrons are lost from one atom and gained by another.
Some properties are:-
They form crystals. ...
They have higher enthalpies of fusion and vaporization than molecular compounds.
They are hard.
They are brittle.
They have high melting points and also high boiling points.
They conduct electricity but only when they are dissolved in water.
an Ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding
Ionic Compounds have high boiling and melting points as they're very strong and require a lot of energy to break.
The electrostatic forces of attraction between oppositely charged ions lead to the formation of ions. Ionic compounds form crystals.
They do not exist as discrete molecules but indeed they are aggregates of oppositely charged ions.
They are very hard crystalline solid. (As because they have strong forces of attraction.)
They have high melting and high boiling point as more energy is required to break the intermolecular force of attraction.
They are soluble ins water(i.e polar solvent) and are insoluble in non-polar solvents like kerosene, ether, petrol, etc.
They can conduct electricity either in molten state or in aqueous solution(aq). They can not conduct electricity in solid-state as the ions are not free.
