Question

why do ionic compound have the high melting and boiling point show electron transfer in MgCl2 and na2o​

Answer 1

Answer:

It takes a lot of energy to overcome the strong electrostatic forces of attraction between oppositely charged ions, so ionic compounds have high melting and boiling points. ... Sodium chloride is made from Na + ions and Cl - ions and has a melting point of 801°C.

Answer 2

Explanation:

Have you ever wondered what happens when metals and non-metals react? They form ionic bonds which form ionic compounds. An ionic bond is the electrostatic force of attraction between two oppositely charged ions. Let’s find out more about it.For e.g. Salt (NaCl) is an ionic bond that 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.
