2009/12/4· ** As a rule, metals generally lose electrons due to their relatively low electronegativity when compared with the elements they react with (Non metals). You won''t really find metals reacting with other metals (Na w/ Mg or something like that), but you can certainly come up with numerous reactions of metals reacting with nonmetals due to the differences in electronegativites.

Sodium Metal: Facts, Dangers And Safety Precautions | …
Sodium Metal: Facts, Dangers And Safety Precautions Science defines sodium as a chemical element that can be represented with the syol Na; its Latin name is natrium, hence the syol. While sodium carries an atomic nuer of 11, it is soft, and has a light silver-white colour.
A new perspective on metals and other contaminants in …
Reportable levels of aluminum, calcium, iron, magnesium, and potassium were found in both the liquid and dry salt fluoride additives and concentration levels were similar in HFS and NaF samples. Concentration levels of potassium and aluminum were higher in the dry salt additives; with aluminum concentrations in the NaF samples nearly 10-fold higher than those in HFS samples.
