There are three main types of chemical bonds: Ionic bonds; Covalent bonds; Metallic bonds (a). Kössel-Lewis Approach to Chemical Bonding: 4. Electrovalent Bond: Electrovalent bond is a type of electrostatic attraction between two atoms. Covalent bonding-this involves sharing of electrons between two or more non metal atoms/elements. Coordinate bond 1. Sep 17, 2018 · This document provides an overview of chemical bonding and molecular structure. Electrons are shared. Solution: Ionic (Electrovalent) Bonding Ionic bonding is a type of bonding where electrons are completely transferred from one atom to another atom or group. 7: Molecular Orbital Theory: 4. , octet) or 2 electrons (i. Give a difference between electrovalent and covalent bonds. The compounds which is formed by ionic or electrovalent bond is known as Jul 19, 2014 · Chemical Bonding. Bond Characteristics .
