WebIonic Bond vs Metallic Bond – Definition. An ionic bond is a chemical bond, in which one or more electrons are wholly transferred from an atom of one element to the atom of the other, and the elements are held together by the force of attraction due to the opposite polarity of the charge. A metallic bond is a chemical bond, in which the atoms ... keith spicer north shieldsWeb4 mrt. 2024 · Metallic bonding. As you can see, an electron is freely moving from one atom to another.
