Question

What are ionic compound explain ( 4 mark questions ) incomplete answer will be reported and good answer will be Mark as brainliest

Answer 1

Compounds that consist ions are known as ionic atoms. Atoms that gain or lose electrons are called ions, ions may have a negative charge or positive charge. Nonmetals lose electrons to gain negative charge and form anions, whereas metals lose electrons to gain positive charge and form cations. Anions are ions that have negative charge and cations are ions that tend to have a positive charge. Ionic bonds are generally between metals and non-metals.

For e.g.  Salt (NaCl) is an ionic bond which consists of Sodium (Na) which is a metal with positive charge combines with Chlorine (Cl), a nonmetal with a negative charge. Another example of an ionic bond is Magnesium Hydroxide Mg(OH)2 which a combination of Magnesium (Mg) and Hydroxide (OH). Here, Magnesium is a metal with cations and Hydroxide is a nonmetal with anions. Iron Oxide (Fe2O3) also known as rust is also an ionic bond, it has metallic compound Iron (Fe) which contains positively charged cations and it has nonmetallic compound Oxygen (O) which contains negatively charged anions

Properties of Ionic Compounds

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.These compounds are brittle and break into small pieces easily.Electrovalent compounds usually dissolve in water and are insoluble in solvents like oil, petrol, kerosene, etc.Ionic compounds do not conduct electricity in a solid state but they do conduct electricity in the molten state.In comparison to molecular compounds, ionic compounds have higher enthalpies of fusion and vaporization.

Answer 2

The compounds which are formed by transfer of electrons from a metal to a non metal are known as ionic compounds or electrovalent compounds.

These compounds does not exist as molecules but aggregates of ion.

These compounds are generally solid due to strong electrostatic force of attraction between oppositely charged ions.

Ionic compounds are good conductors of electricity in aqueous solution or in molten form due to the presence of ions

These compounds are generally soluble in solvents like water but not in other solvents like petrol or kerosene.
