Answer: The second column of the periodic table is known as Group 2 or the alkaline earth metals group. This group includes the following elements:
1. Beryllium (Be)
2. Magnesium (Mg)
3. Calcium (Ca)
4. Strontium (Sr)
5. Barium (Ba)
6. Radium (Ra)
These elements are called alkaline earth metals because they share similar chemical properties. They are all shiny, silvery-white metals that are relatively reactive but less reactive than the elements in Group 1 (alkali metals). Alkaline earth metals have two valence electrons in their outermost energy level, making them relatively likely to lose these electrons and form positive ions with a +2 charge.
These elements have a variety of uses and applications. For example, magnesium is used in the production of lightweight alloys, calcium is important for bone health, and barium compounds are used in X-ray imaging. Overall, the elements in Group 2 have important roles in various industries and biological processes.
