why ionic compounds have high melting point and boiling point?
8214
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.

Individual ions within an ionic compound usually have multiple nearest neighbours, so are not considered to be part of molecules, but instead part of a continuous three-dimensional network, usually in a crystalline structure. ... Ionic compounds typically have high melting and boiling points, and are hard and brittle.

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.

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. ... The greater the charge on the ions, the stronger the forces holding them together.

Explaining melting points 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.

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.

High thermal stability - Ionic liquids usually have very high thermal stability. This greatly increases the operating temperature of the system and allows one to make specialized batteries for high-temperature applications such as down-hole drilling, engine sensors, etc.

Ionic compounds are named for their positive metal ion first, followed by their negative nonmetal ion. 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.

Explanation: Ionic species are essentially non-molecular with NO molecular boundaries. Given the fact that there are no discrete molecules and strong electrostatic interaction between ions it takes a lot of energy to disrupt the interaction, and this manifests in high melting and boiling points.

Some of the properties of ionic solids are high melting point, low vapor pressure, brittleness and the inability to conduct electricity. Ionic compounds can be readily dissolved by polar molecules like water.
1474355
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.

Ionic compounds have high melting points because there is a strong electrostatic force of attraction between the oppositely charged ions and hence a large amount of energy is required to break the strong bonding force between ions..

Ionic compounds tend to have higher melting and boiling points than covalent compounds. Ionic compounds tend to be hard and brittle while covalent compounds tend to be softer and more flexible. Ionic compounds conduct electricity when dissolved in water while covalent compounds typically don't.

Ionic compounds have ionic bonds and molecular compounds have covalent bonds. ... Ionic compounds have higher melting and boiling points compared to molecular compounds. Ionic compounds conduct electricity in their molten state and in their aqueous solutions. Molecular compounds are poor conductors of heat and electricity.

Properties of ionic compounds. Ionic compounds have regular structures, called giant ionic lattices . In a giant ionic lattice, there are strong electrostatic forces of attraction acting in all directions between the oppositely charged ions.

Ionic compounds tend to have high melting and boiling points, because the attraction between ions in the lattice is very strong. Moving ions out of the lattice disrupts the structure, so ionic compounds tend to be brittle rather than malleable.
