General physical properties that can be explained by the covalent bonding model include boiling and melting points, electrical conductivity, bond strength, and bond length.

['They are solid (with the exception of mercury, Hg, a liquid).', 'They are shiny, good conductors of electricity and heat.', 'They are ductile (they can be drawn into thin wires).', 'They are malleable (they can be easily hammered into very thin sheets).']

In ionic compounds, electrons are tightly held by the ions, and the ions cannot move translationally relative to each other. This explains many properties of ionic solids. They are hard and brittle, they are not malleable or ductile (i.e. cannot be shaped without cracking/breaking), and they do not conduct electricity.

We learned that physical properties are things like shininess, conduction of heat or electricity, melting point, and density. Chemical properties include things like reactivity to oxygen, flammability, and ability to hold on to electrons during a chemical reaction.

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 compounds are generally combinations of metals and non-metals. Molecular compounds are general combinations of non-metals only. Pure ionic compounds typically have their atoms in an organized three dimensional arrangement (a crystal).

High melting points and boiling points Ionic compounds have high melting and boiling points, so they are in the solid state at room temperature.

a) Ionic compounds b) Metals c) Water. Ionic compounds in the solid state do not conduct electricity because movement of ions in the solid is not possible due to their rigid structure.

Ionic crystals are hard, have high melting points, and are brittle. When they melt, the resulting liquids conduct electricity well. These properties reflect the strong attractive forces between ions of opposite charge as well as the repulsions that occur when ions of like charge are placed near each other.

Covalent compounds have bonds where electrons are shared between atoms. Due to the sharing of electrons, they exhibit characteristic physical properties that include lower melting points and electrical conductivity compared to 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.']

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 many uses in industry.

Ionic compounds are compounds consisting of ions. Two-element compounds are usually ionic when one element is a metal and the other is a non-metal. Examples include: sodium chloride: NaCl, with Na+ and Cl- ions.
