Introduction

• A series of elements comprising Group 2 ( column 2) of the periodic table:
• beryllium (Be)
• magnesium (Mg)
• calcium ( Ca)
• strontium ( Sr)
• barium ( Ba)
• radium ( Ra)

Characteristics

• silver colored, soft metals
• react readily with halogens to form ionic salts
• react with water (not as rapidly as the alkali metals) to form strongly alkaline hydroxides

• magnesium reacts only with steam
• calcium reacts with hot water
• beryllium does not react with water or steam, & its halides are covalent.

• alkaline earth metals have 2 electrons in their valence shell, thus a tendency lose two electrons to form divalent cations

More General Terms

• chemical element
• metal
