Alkaline Earth Metal

 

The alkaline earth metals (beryllium, magnesium, calcium, strontium, barium, and radium) are the second most reactive metals in the periodic table, and, like the Group 1 metals, have increasing reactivity in the higher periods. the alkaline earth metals are so reactive that they are never found in elemental form in nature. Because they form +2 ions that have very negative reduction potentials
