The explanation for the respective melting point of sodium ( Na ; 89 ° C ) and potassium ( K ; 63 ° C ) is to be determined. Concept introduction: Metallic bonds are formed between metals. A metallic bond is formed between positively charged ions in a sea of delocalized electrons. The electrons in metals are delocalized over the entire metal. The metallic character is characterized by the tendency of metals to lose their outermost valence shell electrons. Greater the ease of electron removal, higher will be the electropositivity of the corresponding elements and vice versa. Melting point is the temperature of a substance at which solid form of the substance melts to liquid form.
