  • Chapter 6 Chemistry Complete And Verified Chemical Bonds Chemical bonds are formed through the mutual electrical attraction between the nuclei and valence electrons of different atoms. This attraction binds the atoms together, forming a chemical bond. Types of Chemical Bonds Ionic bonding occurs when there is an electrical attraction between large numbers of cations and anions. Covalent bonding, on the other hand, results from the sharing of electron pairs between two atoms. Pola...
