What are some fun facts about the alkaline-earth metals?
The alkaline earth elements are metallic elements found in the second group of the periodic table. All alkaline earth elements have an oxidation number of +2, making them very reactive. Because of their reactivity, the alkaline metals are not found free in nature. The Alkaline Earth Metals are: * Beryllium (Be) * Magnesium (Mg) * Calcium (Ca) * Strontium (Sr) * Barium (Ba) * Radium (Ra) The alkaline earth metals are a series of elements comprising Group 2 of the periodic table. This specific group in the periodic table owes its name to their oxides that simply give basic alkaline solutions. These elements melt at such high temperature that they remain solids (“earths”) in fires. The alkaline earth metals provide a good example of group trends in properties in the periodic table, with well-characterized homologous behavior down the group. With the exception of Be and Mg, the metals have a distinguishable flame color, orange-red for Ca, magenta-red for Sr, green for Ba and crimson red fo
