why do ionic compounds have high melting point answer?
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.

Ionic compounds have an equal number of positive and negative ions arranged in the three-dimensional lattice due to which they have high melting points. The strong force of attraction between oppositely charged ions means that ionic compounds have high melting and boiling points.

Ionic solids—Made up of positive and negative ions and held together by electrostatic attractions. They're characterized by very high melting points and brittleness and are poor conductors in the solid state. An example of an ionic solid is table salt, NaCl.

In ionic compounds, there exists a strong force of attraction between the oppositely charged ions, so a large amount of energy is required to break the strong bonding force between the ions. That is why ionic compounds have high melting and boiling point.

Ionic compounds High melting points:- There are many strong forces to overcome before the ions can be freed from their positions in the lattice. Volatility:- Very low for the reasons outlined above. ... Solubility: Charged particles such as ions can easily form bonds to polar solvent molecules, such as water.

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. However, some have higher melting points than others. The greater the charge on the ions, the stronger the forces holding them together.

High melting points 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.

Why do ionic compounds tend to be hard and brittle? The cations and anions are locked tightly into place because of the attraction of their opposite charges - as a result, it's difficult to move the ions and the material is very hard. ... This makes ionic compounds very brittle.

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. ... These compounds are brittle and break into small pieces easily.

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.

The reason why ionic compounds are hard and brittle is because the ions in the compound are already held rigidly in place in a lattice due to the strong electrostatic forces of attraction in between the cations and the anions as well as the repulsion in the ions with like charges .

The melting and boiling points of molecular compounds are generally quite low compared to those of ionic compounds. This is because the energy required to disrupt the intermolecular forces between molecules is far less than the energy required to break the ionic bonds in a crystalline ionic compound (Figure 6.2. 1) .
