y do ionic compounds have high melting point?
479260
The more energy needed, the higher the melting point or boiling point . Since the electrostatic forces of attraction between oppositely charged ions are strong, their melting and boiling points are high.

Anna stated that ionic compounds have high melting points and low boiling points. She said that this demonstrates that ionic compounds have strong bonds because a lot of energy is needed to break the electrical forces that hold the bonds together.

Ionic Solid Ionic solids tend to have high melting points ("high" generally being higher than metallic but lower than covalent). Because the electrons in ionic solids are localized (in the ions) these solids tend to be stiff and brittle like covalent solids.

These ionic bonds between the charged particles result in a giant structure of ions. Because the ions are held together tightly in this giant structure it takes a lot of energy to break all the bonds. As a result, ionic compounds have high melting and boiling points.

Ionic compounds have high melting points. The electrostatic attraction (ionic bond) between cations and anions is strong. It takes a lot of energy to overcome this attraction in order to allow the ions to move more freely and form a liquid. ... The charge on the ions.

So, there exists a strong electrostatic force. ... Thus, ionic compounds have atoms bound by stronger electrostatic force than in case of covalent compounds. So, in general it is easier to break covalent bonds than ionic bonds. Thus, the melting and boiling points of ionic compounds are greater than covalent compounds.

Why do ionic compounds have high melting and boiling points? This is because of the strong attractive electrostatic forces holding the oppositely charged ions together and a large number of ionic bonds in the crystal lattice.

Answer: Low melting points and electrical conductivity in solids are not common properties of ionic solids.

High melting and boiling points - Ionic bonds are very strong - a lot of energy is needed to break them. So ionic compounds have high melting and boiling points. Conductive when liquid - Ions are charged particles, but ionic compounds can only conduct electricity if their ions are free to move.

Network solids have similar properties to ionic solids. They are very hard, somewhat brittle solids with extremely high melting points (higher than 1,000 C or 1,800 F). Unlike ionic compounds, they do not dissolve in water, nor do they conduct electricity.

Ionic compounds consist of oppositely charged ions that are held together by ionic bonds. ... Ionic compounds are solids with high melting and boiling points. They are good conductors of electricity but only when dissolved in water. Their crystals are rigid and brittle.

Ionic compounds have high melting and boiling points, so they are in the solid state at room temperature. See the study guide on the three states of matter to see how bonding and structure are related to the properties of substances. Energy must be transferred to a substance to make it melt or boil.

Ionic compounds are held together by electrostatic forces between the oppositely charged ions . ... As the ionic lattice contains such a large number of ions, a lot of energy is needed to overcome this ionic bonding so ionic compounds have high melting and boiling points.

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.
