Web8 Dec 2013 · 13. ALKALINE EARTH METALS Also called as Group II A elements. All alkaline earth elements have an oxidation number of +2, making them very reactive. Because of their reactivity, the alkaline earth metals are not found free in nature. Beryllium (Be), Calcium (Ca), Strontium (Sr), Barium (Ba) , and Radium (Ra) 14. WebAn unusual trend in the group 1 elements is the smooth decrease in the melting and boiling points from Li to Cs. As a result, Cs (melting point = 28.5°C) is one of only three metals (the others are Ga and Hg) that are liquids at body temperature (37°C). Table 21.3 Selected Properties of the Group 1 Elements.
