Trisodium heptaphosphide Na3P7 (1) reacts with alkyl tosylates with formation of sodium dialkylheptaphosphides (2) or trialkylheptaphosphines (3) depending on the stoichiometry. Sodium 1,2-diphosphacyclopentadienide is formed in the reaction of cyclopropenyl complexes of nickel with sodium poly...
Chemical Properties of Alkali Metals Alkali metals are theleast electronegative(most electropositive) elements in the periodic table due to a presence of asingle valence electronthat is donated very easily. This allows them to readily react with many nonmetals; in fact, they are the most reactive...

Chemical Properties of Alkali Metals Every element has a nucleus, made up of protons and neutrons, and alkali metals are no different. Surrounding the nucleus of atoms are electrons, which are particles with a negative charge. These electrons exist inenergy shellsaround the nucleus of the atoms,...

Alkali Metal Properties The alkali metals exhibit many of the physical properties common tometals, although their densities are lower than those of other metals. Alkali metals have one electron in their outer shell, which is loosely bound. This gives them the largest atomic radii of the elements...

The occurrence, metallurgical extraction methods, chemical properties, and prominent applications, including those of the compounds of alkali metals—lithium, sodium, and potassium—have been described. Alkali metals are excellent reductants for other metal compounds, since alkali metals form some of the...
