CHEMICAL BONDS

 Introduction 

Chemical bonds and structure of molecules are conceptual models based on the modern atomic model, in order to explain the physical and chemical properties of matter.Many atoms do not have stable outermost valance shell configurations, therefore chemical bonds occur between atoms in order to achieve stability. The following data explains how valence electrons participate in different types of chemical bonding using several acceptable models.

Chemical bonds

👉Sharing a pair of electrons between two atoms

1.Covalent bonds

Sharing a pair of electrons between two atoms in which each atom contributes one electron

2.Dative covalent bonds

Sharing of an electron pair between two atoms in which both electrons are given by one atom

👉Metallic bonds

Large numbers of metallic cations are stabilized by a cloud of many electrons

👉Co Complete removal of electrons from an atom to form cations and acceptance of electrons by another atom 

1.Ionic bonds/ Ionic interactions/ Ionic attraction forces

Formed due to electrostatic attractive forces between cations and anions
