WebGroup 2, also known as the alkaline earth metals, is a group of metals in the periodic table. Group 2 contains the elements beryllium, magnesium, calcium, strontium, barium, and radium. Group 2 elements each have two electrons in their outer shell. Atomic radius, reactivity, and solubility of group 2 hydroxides increase as you move down the group. WebThe first two are in the inner orbit (same as He) and the other two are in the outer orbit that can hold eight electrons. Therefore, Be can either donate these two electrons, or accept … lawn chairs canada
