The major reason for chemical bonding is for atoms to gain the stability of the octet

Explanation:

During the course of a chemical reaction dissociation of bonds and formation of new bonds takes place which is responsible for formation of new substance as a product.

When a formation of chemical bonds takes place sharing or transfer of electrons takes place. This is because some elements looses electrons and some elements gains electrons so as to attain stability of fully filled electronic configuration or complete octet.

Here, carbon atom has 4 electrons in its valence shell and need 4 more electrons to complete its octet where as oxygen atom requires two more electrons to completes its octet.So, carbon by sharing its both electron pair with two oxygen atoms forms a stable product that is carbon-dioxide.

the pseudoscience are like beliefs, theories, or like practices that are considered scientific
