Answer : In alkali metals, on moving down the group, the atomic size increases and the effective nuclear charge decreases. Q. They are related to the Alkali metals, but they do not react as much because they need more energy to remove their two electrons. Alkaline earth metals have higher melting and boiling points, than alkali metals because of smaller size. Alkaline-earth metal - Alkaline-earth metal - Physical and chemical behaviour: The alkaline-earth elements are highly metallic and are good conductors of electricity. Low Ionization Energy Valence Electron Configuration Effective Nuclear Charge Alkaline Earth Metal Alkaline Earth Metals. So they do not have to be stored in petrol.

Together with hydrogen they constitute group 1, which lies in the s-block of the periodic table.All alkali metals have their outermost electron in an s-orbital: this shared electron configuration results in their having very similar characteristic properties. 30 seconds . All the elements in this group … The elements highlighted in yellow on the periodic table in the graphic belong to the alkaline earth element group. The alkaline earth metals are a group of elements in the periodic table. Beryillium. Electropositivity increases down the group from Be to Ba. The alkaline earth metals are the elements that correspond to group 2 of the modern periodic table. Group II elements include; Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba) and Radium (Ra). Alkali and Alkaline Earth Metals : Q & A . Group 1 Alkali metals. Beryllium is sufficiently hard to scratch glass, but barium is only slightly harder than lead. For shortcuts to this section, see the alkaline earth metals. Group 2: The Alkaline Earth Metals. Beryllium is unusual and is not studied at GCSE. All alkali metals are highly reactive towards the more electronegative elements such as oxygen and halogens. Here we discuss about occurrence, reactions, physical properties of alkaline earth metals. • Beryllium is not typical of the group, however, and is thus not considered here. This enables the metals to easily lose the electrons which increases their stability and allows them to form the compounds. The fluorides of alkaline earth metals, except beryllium fluoride, are insoluble in water because of large values of their lattice energy.
