The electrostatic forces of attraction between the metallic ions and free electrons is called

The electrostatic forces of attraction between the metallic ions and free electrons is called "Metallic Bond." Metallic bonding is a type of chemical bonding that holds together metals in solid-state structures, allowing them to conduct electricity and heat, and exhibit unique mechanical properties like malleability and ductility.

In metallic bonds, the valence electrons of metal atoms are delocalized, meaning they are not associated with any particular atom but are distributed throughout the entire crystal lattice. These delocalized electrons create a "sea of electrons" that surrounds the positively charged metal ions. This sea of electrons attracts the metallic ions and acts as a glue that holds the metal lattice together. The electrostatic forces of attraction between the positively charged metal ions and negatively charged delocalized electrons are what create the metallic bond. This results in the unique properties of metals, such as their ability to conduct electricity and their high melting and boiling points. To reiterate, the term that describes the electrostatic forces of attraction between metallic ions and free electrons is called "Metallic Bond."
