The bond consists of a series of metal atoms that have all donated their valence to an electron cloud that permeates the structure. This electron is frequently referred to as an sea. It might help to visualize the electron sea model as if it were a box of marbles that are surrounded by water. The marbles represent the metal atoms and the water represents the sea.

Since the metal atoms have all lost their valence , they are now all identical to positively charged ions. However, because they are not associated with ionic bonding, these positively charged ions have a special name. The positively charged ions within a metallic solid are known as Kernels.

The mechanism that holds a bond together is the attraction between the kernels and the electron sea. The strength of the metallic bond is derived primarily from the charges in the system.

The larger the magnitude of the positive charge on the metallic nuclei, the greater the strength of the bond.

The greater the number of valence contributed to the electron sea, the greater the strength of the bond.
