A covalent bond involves: <u>d. sharing electrons</u>
The atoms of a molecule are held together by electrical forces that hold the atoms together, this is due to the electrical attraction between the electrons of the atom of one element and the nucleus of the other atom, this force of attraction is called covalent bond.
A covalent bond involves the sharing of electrons that are in the last energy layer of the atoms because they are the most likely or willing to be shared.
An example of a covalent bond is the bond between a hydrogen atom and a carbon atom in methane.
