Covalent bonding:
One or more electrons transfers from each atom of the metal to each atom of the non-metal
Do not involve the sharing or transfer of electrons, used to bond large molecules such as proteins and nucleic acids
Atoms overlap slightly, and one unpaired electron from each atom will pair together
Ionic bonding:
One or more electrons transfers from each atom of the metal to each atom of the non-metal
Do not involve the sharing or transfer of electrons, used to bond large molecules such as proteins and nucleic acids
Atoms overlap slightly, and one unpaired electron from each atom will pair together
Non-covalent bonding:
One or more electrons transfers from each atom of the metal to each atom of the non-metal
Do not involve the sharing or transfer of electrons, used to bond large molecules such as proteins and nucleic acids
Atoms overlap slightly, and one unpaired electron from each atom will pair together
