WitrynaThe alkaline earth metals are the elements that correspond to group 2 of the modern periodic table. This group of elements includes beryllium, magnesium, calcium, strontium, barium, and radium. The elements of this group are quite similar in their physical and chemical properties. For example, all alkaline earth metals are silvery-white ... The reactivity series is sometimes quoted in the strict reverse order of standard electrode potentials, when it is also known as the "electrochemical series". The following list includes the metallic elements of the first six periods. It is mostly based on tables provided by NIST. However, not all sources give the same values: there are some differences between the precise values given by NIST and the CRC Handbook of Chemistry and Physics.

Witryna8 lis 2024 · The order of reactivity of the alkali metals towards hydrogen decreases as we move down the group from Li to Cs. This is due to the reason that the lattice energies of these hydrides decreases progressively as the size of the metal cation increases and thus the stability of these hydrides decreases from LiH to CsH.

WitrynaReactions of Alkali Metals With Water . The alkali metals react with water to form metal hydroxides and release hydrogen gas. 2M(s) + 2 H 2 O(l) 2MOH(aq) + H 2 (g) Reaction of the alkali metal with water is exothermic and the enthalpy of the reaction increases from Lithium to Caesium. Alkali metals float in the water during the reaction. WitrynaLithium, sodium, potassium, rubidium, caesium and francium belongs to alkali metals. We see, reaction rate of group 1 metals with water increases when going down the group. Therefore, all group 1 metals should react with water. But, due to rareness of francium, experiments may be not done to test its reactivity with water.
