This group usually contain smooth, silver metals with a less metallic character than the elements of Group 1. false, 2. The alkaline earth metals are a family of chemical elements that make up the second group of the modern periodic table. Uses of Alkaline Earth Metals. Moreover, enthusiasts are also catered with the detailed breakdown of the atomic, optical and chemical behaviour of the metals. 1) It is used in the manufacture of alloys. Alkaline earth metals (Be,Mg,Ca,Sr,Ba,Ra) have similar and different characteristics to alkali metals. As can be seen from Figure \(\sf{\PageIndex{2}}\), Alkaline earth metals' possess large negative M 2+/0 standard reduction potentials which strongly favor the +2 cation. 2) Metallic beryllium is used for making Windows of X- ray tubes. The alkaline earth metals tend to form +2 cations. Learn more about the Alkaline Earth Metals for IIT JEE ( Main and Advanced) at Vedantu.com. (i) The general electronic configuration of alkaline earth metals is [noble gas] ns 2. d. True or false: All alkaline Earth metals have three valence electrons.
