Web29 sep. 2024 · They are less reactive because they have 2 electrons in the outer shell of the atoms and they like to be full and the alkali metals only have 1 electron in the outer shell of the atom, and it is easyer to give away 1 electron than 2 so they are more reactive than other elements. The electronegativity (Pauling values) is lower for the alkali metals. Web13 mrt. 2015 · It was noted as early as 1918 that solutions of alkali metals or alkaline earths in methylamine had an absorption maximum at 650 nm in addition to the increased infrared (IR) absorption of the solvated electron . Many other studies since that time have shown this peak in Li, Na, K, Rb and Cs solutions in amines and polyethers.
