Calculate the formal charge of C in CH4.

Chemical Bond is a force that acts between 2 or more atoms to hold them together as a stable molecule. The Kossel-Lewis approach to chemical bonding, also known as Lewis theory, is a concept that explains how chemical bonds form by the transfer (ionic bonding) or sharing (covalent bonding) of electrons in the outermost shell of atoms to achieve a stable electron configuration, usually an octet (eight electrons).
