what are the physical properties of ionic bonds?
433777
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.

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.

The Condition required for the formation of an ionic bond between two Elements are: Two elements must be of opposite charge. An element must have its less Ionisation Enthalpy(Cation). Another element must have high negative electron gain enthalpy(Anion).

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.

Different types of chemical bonds and their varying intensity are directly responsible for some of the physical properties of minerals such as hardness, melting and boiling points, solubility, and conductivity. Chemical bonds also influence such other properties as crystal symmetry and cleavage.

Ionic bonds are formed through the exchange of valence electrons between atoms, typically a metal and a nonmetal. The loss or gain of valence electrons allows ions to obey the octet rule and become more stable. Ionic compounds are typically neutral. Therefore, ions combine in ways that neutralize their charges.

When ionic compound melts , long range network of ionic bonds changes into short network of ionic bonds. When ionic compound boils , then ionic bonds are decreased to almost zero. In molecular solids, basic units are molecules.

Chemical bonds include covalent, polar covalent, and ionic bonds. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds. Atoms with large differences in electronegativity transfer electrons to form ions. The ions then are attracted to each other.

The physical and chemical properties of covalent compounds tend to vary much more than they do for ionic compounds. These compounds may be solids, liquid or gases at room temperature. They are not usually electrically conductive. Polar covalent compounds are soluble in water but nonpolar ones are not.

Ionic Bonds Ionic bonding is a type of chemical bond in which valence electrons are lost from one atom and gained by another. This exchange results in a more stable, noble gas electronic configuration for both atoms involved.
