How NaK bond?

NaK, an alloy of sodium (Na) and potassium (K), forms through metallic bonding. In this bond, the valence electrons from both sodium and potassium are delocalized, creating a "sea of electrons" that allows for conductivity and malleability. The interaction between the positively charged metal ions and the electron cloud holds the atoms together, resulting in a stable metallic structure. NaK is often used in applications like heat transfer and as a coolant due to its low melting point and liquid state at room temperature.
