Group 2: General Properties - Chemistry LibreTexts

Introduction. Group 2 contains soft, silver metals that are less metallic in character than the Group 1 elements. Although many characteristics are common throughout the group, the heavier metals such as Ca, Sr, Ba, and Ra are almost as reactive as the Group 1 Alkali Metals.All the elements in Group 2 have two electrons in their valence shells, giving them an oxidation state of +2.

Calcium plays a vital role in the anatomy, physiology and biochemistry of organisms and of the cell, particularly in signal transduction pathways. More than 500 human proteins are known to bind or transport calcium.The skeleton acts as a major mineral storage site for the element and releases Ca2+ ions into the bloodstream under controlled conditions.

What are the most reactive elements in the periodic table

Nov 01, 2007· Best Answer: The alkali metals are the most reactive metals. I''m not sure how the activity of francium relates to the other metals in the group because it''s sooooo incredibly rare. However, of the more common metals, either lithium or potassium has the greatest reactivity (depending on which activity series you look at, apparently).
