properties of alkaline earth metals

                          The name alkaline earth metals was given to magnesium, calcium, barium & strontium since their oxides were alkaline in nature and these oxide remained unaffected by heat or fire and existed in earth. Alkaline earth metals are reactive but less than alkali metals. On moving down the group their atomic and ionic radii increase due to the decrease in their effective nuclear charge. ��_� �DDjgl`�Q1�H � �5�� false, alkali metals.
