Final answer:
The bond between two nonmetals is a covalent bond, involving the sharing of electrons to fill their outer electron shells. The electronegativity of nonmetals is similar,
Step-by-step explanation:
When two nonmetals form a bond, it is typically a covalent bond. This type of bonding occurs when the sharing of electrons between nonmetals takes place, allowing them to fill their outermost shell with electrons for increased stability. The shared electrons move in orbitals around both atoms, creating an attractive force between the negatively charged electrons and the positively charged nuclei, thereby holding the atoms together.
Nonmetals have similar electronegativities, and as a result, the shared electrons in a covalent bond are not drawn significantly more towards one atom than the other, often resulting in nonpolar covalent bonds. When electrons are shared unequally due to a difference in electronegativity, polar covalent bonds are formed. Unlike ionic bonds, which form through the transfer of electrons from metals to nonmetals leading to the creation of charged ions, covalent bonding involves the mutual sharing of electrons between nonmetal atoms.
