Final answer:
Covalent bonds involve sharing electrons between nonmetals, ionic bonds involve the transfer of electrons between metals and nonmetals, and metallic bonds involve the sharing of electrons between metal atoms.
Step-by-step explanation:
The three types of chemical bonds are covalent bonds, ionic bonds, and metallic bonds.
Covalent bonds occur when two atoms share electrons. These bonds are formed when nonmetal atoms bond with each other. Covalent bonds are strong, as the shared electrons create a stable arrangement of atoms.
Ionic bonds are formed when one atom gives up electrons and another atom accepts those electrons. These bonds occur between a metal and a nonmetal. Ionic bonds are strong and form crystal structures.
Metallic bonds occur when metal atoms share electrons in a sea of mobile electrons. These bonds are responsible for the high electrical and thermal conductivity of metals. Metallic bonds are typically weaker than covalent or ionic bonds.
In summary, covalent bonds involve sharing electrons between nonmetals, ionic bonds involve the transfer of electrons between metals and nonmetals, and metallic bonds involve the sharing of electrons between metal atoms.
