What happens to the electrons in a completely covalent bond?

Explanation:

Covalent bonding occurs when pairs of electrons are shared by atomsAtoms will covalently bond with other atoms in order to gain more stabilityand is gained by forming a full electron shell.sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability._________________________________

Ch4 is nonpolar and insoluble in water. since all of the hydrogen atoms are evenly spread around the carbon atom even through the c h bond is polar all the poles cancel each other out.
