Final answer:
Covalent bonds represent how atoms are bonded together in a molecule by sharing a pair of electrons.
Step-by-step explanation:
The molecule formula special how atoms are bonded together is represented by covalent bonds. Covalent bonds involve the sharing of a pair of electrons between atoms. This type of bond can result in either polar covalent or nonpolar covalent bonds, depending on the electron sharing. Ionic bonds involve the transfer of electrons, while metallic bonds involve the sharing of electrons in a sea of delocalized electrons.
