lonic bonds are the interactions between a cation and an anion. Metals tend to form cations giving a discrete positive charge while nonmetals tend to form anions having a negative charge. These charges were developed as the atoms were attempting to satisfy the octet rule; however, Nature prefers matter to be electronically neutral. This results in ionic compounds between metals and nonmetals which have literally transferred their electrons and are now forced together simply based on the electrostatic interaction between positive and negative charges. This electrostatic interaction is so strong in an ionic bond, that melting and boiling points are very high. K. [K]* |K|*|::] BONO S CI [:c₁:] potassium chloride 4. Fill in the following table.

Types of Chemical Bonds
The attractive force which has the ability of holding various constituent elements like atoms, ions, molecules, etc. together in different chemical species is termed as a chemical bond. Chemical compounds are dependent on the strength of chemical bonds between its constituents. Stronger the chemical bond, more will be the stability in the chemical compounds. Hence, it can be said that bonding defines the stability of chemical compounds.
Polarizability In Organic Chemistry
Polarizability refers to the ability of an atom/molecule to distort the electron cloud of neighboring species towards itself and the process of distortion of electron cloud is known as polarization.
Coordinate Covalent Bonds
A coordinate covalent bond is also known as a dative bond, which is a type of covalent bond. It is formed between two atoms, where the two electrons required to form the bond come from the same atom resulting in a semi-polar bond. The study of coordinate covalent bond or dative bond is important to know about the special type of bonding that leads to different properties. Since covalent compounds are non-polar whereas coordinate bonds results always in polar compounds due to charge separation.
