Question

Give the classification of covalent bond along with examples.​

Answer 1

Answer:

Covalent bonding occurs between non-metal elements when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms to attain the nearest noble gas electron configuration. Here when elements share their electrons, they do not become positive or negative, since they are neither gaining nor sacrificing electrons. Thus no ions are formed by covalent bonding. Based on the number of shared electron pairs, there are three types of covalent bond. Namely, single covalent bond, double covalent bond and triple covalent bond.

Covalent Bonding of Hydrogen Molecule

• The simplest way to learn about the covalent bond is the example of a hydrogen molecule. Are you aware that hydrogen that is present in our atmosphere cannot exist in its original form? It has to bond with another atom, for it to be stable enough. This is why the molecular formula of hydrogen is always H2.
