However, the adduct has two π coordinated lithium dietherate molecules sitting on either side of the heterocycle, which prevent it from being considered a classic aromatic species. Reactions of Alkaline Earth Metals. The alkaline earth metals are less reactive and thus more difficult to initiate a reaction when compared to the alkali metals. These were called earths by early chemists. In chemical terms, all of the alkaline metals react with the halogens to form ionic alkaline earth metal halides. All alkaline Earth metals have similar properties because they all have two valence electrons. Ed., 2014, 53, 5634 (DOI: 10.1002/anie.201310116), 3 L A Freeman et al, Inorg.

Alkaline-earth metal, any of the six chemical elements that comprise Group 2 of the periodic table. The reaction of alkali metals with water is represented by the following equation: 2 M(s or l) + 2 H 2 O (l) --> 2 M(OH) 2 (aq) + H 2 (g) Where M is the alkali metal.The heat given off by this reaction immediately melts the sodium and potassium and is frequently sufficient to ignite the hydrogen gas produced: The burning Mg ribbon produces an intense white light and ash residue. The reactivity of alkali metals increases from Li to Cs, since the ionisation energy decreases down the group. To show the differences in reactivity and the periodic trend of reactivity between alkaline earth and alkali metals. true. What distinguishes a metal from a nonmetal?

Further evidence of the molecule’s aromaticity came from the beryllium atom’s nuclear magnetic resonance shift, as well as from computational orbital and magnetic shielding analysis. In contrast to the high reactivity of the alkaline earth metal organic compounds, the bulk metals themselves which are often used as starting materials, are fairly unreactive. In 2014, chemists described a magnesiacyclopentadiene, which they calculated to be antiaromatic.2 But the compound’s structure couldn’t be confirmed, so its antiaromaticity remained theoretical.
