Metallic Bond .
A metallic bond
Number of valence electrons-The greater the number of freely mobile valence electrons, the higher the charge of positive metal ion, the stronger the metallic bond. Size of metal atom or ion-The smaller the size of the metal ion, the closer the nuclei of metal cations are to the delocalized mobile electrons, the stronger the forces of attraction between the electrons and nuclei, the stronger the metallic bonds.
A metallic bond is what allows metals to be flatten. Metallic bond also allows medal to be shaped.
A metallic bond is characterized by overlapping atoms.
The metallic bond in aluminum is stronger than in sodium because aluminum has more valence electrons that can be delocalized and contribute to the bond strength. This results in a higher charge density and stronger attraction between the metal atoms and the delocalized electrons, compared to sodium which has fewer delocalized electrons due to its lower number of valence electrons.
Metallic
The number of valence electrons determines the strength of the metallic bond. The more the stronger the bond will be.
A metallic bond would be expected between two sodium atoms. In metallic bonding, electrons are delocalized and move freely between atoms, holding them together in a lattice structure. Sodium is a metal and tends to form metallic bonds with other sodium atoms.
Ionic bond
metallic bond
Ionic bonds hold sodium atoms together. Sodium atoms lose an electron to achieve a stable electron configuration, forming positively charged sodium ions. These ions are then attracted to negatively charged ions from other elements to form a bond.
As the size of Na is smaller than the size of K,NaCl will have stronger bond than KCl
Sodium and magnesium can form an ionic bond, where sodium donates an electron to magnesium, resulting in the formation of positively charged sodium ions and negatively charged magnesium ions that are attracted to each other.

Metallic bonding. Sodium ions only bond to each other in sodium metal.
There is a direct relationship between metallic bond strength and enthalpy of vaporization. Stronger metallic bonds require more energy to break, resulting in a higher enthalpy of vaporization. This means that metals with stronger metallic bonds will have higher enthalpies of vaporization.
