How is a metallic bond different from an ionic and covalent bond?

Answer 1

While electrons are transferred in ionic bond and shared in covalent bond, in metallic bonds electrons may move freely and they are not bound to any particular proton. This is called the electron sea theory. The significance of this type of bonding is, metal becomes malleable (because the electrons can just shift place instead of breaking down the bond when metal is pressurized) and a good electricity conductor (because of the freely moved electrons).

Answer 2

In a metallic bond, electrons are delocalized and free to move throughout the metal lattice, giving metals their unique properties like malleability and conductivity. In an ionic bond, electrons are transferred from one atom to another, creating positively and negatively charged ions that are held together by electrostatic forces. In a covalent bond, electrons are shared between atoms to achieve stability, forming strong bonds between the atoms.
