Web6 dec. 2024 · Group 1 metals are less reactive than group 2 metals. Its valence shell contains 2 electrons. They have low electronegativity. Compounds of alkali metals are often insoluble in water. Alkaline metals are usually Shiny, silvery. They have ions with a +2 charge. They are solid. They are harder, denser, stronger. Two earlier group number systems exist: CAS (Chemical Abstracts Service) and old IUPAC. Both use numerals (Arabic or Roman) and letters A and B. Both systems agree on the numbers. The numbers indicate approximately the highest oxidation number of the elements in that group, and so indicate similar chemistry with other elements with the same numeral.
