Chemical Bonding and Structure

In his essay I will be discussing the scientific background and explanation of chemical bonding and structure, I will also be describing the method of injection molding and its benefits and limitations and how it is superior to the previous methods of making plastic. Finally I will also list the implication effect of plastic and its effect (economically and environmentally)

A chemical bond is the result of a lure (attraction) between atoms or ions. The different sorts of bonds that a molecule contains will determine its physical properties, including melting point, hardness, electrical and thermal conductivity, and solubility.

How do chemical bonds occur?
Chemical bonding occurs when two atoms with unfull valence orbitals react and exchange or share electrons; the result is either a covalent bond (shared electrons so that each has a full shell) or an ionic bond (the electron is completely removed from one atom and given to the other; the differently charged ions then attract and bond).

1. Covalent bonding

Gilbert Newton Lewis (October 23, 1875 – March 23, 1946)[2] was an American physical chemist known for the discovery of the covalent bond and his concept of electron pairs; his Lewis dot structures and other contributions to valence bond theory have shaped modern theories of chemical bonding. Lewis has successfully contributed to thermodynamics, photochemistry, and isotope separation, and is also known for his concept of acids and bases.

A covalent bond is a bond concerning two non-metallic elements. This means that they share electrons inside the molecules. It is a type of chemical bond in which there is a sharing of electrons between two atoms is called covalent bond. It is further classified into single, double, and triple covalent bond depending on how many electrons are being shared. For example if 2 electrons are being shared, it is a double covalent bond; if only 1 is being shared it is
