The elements located in group II of the periodic table of the elements are known as alkaline earth elements. These are all metals and include beryllium, magnesium, calcium, strontium, barium and radium. The various uses of these elements are listed below:
Beryllium: commonly used in the medical industry, in x-ray tubes. It has military applications as well.
Magnesium: a key constituent of chlorophyll and hence is critical to the process of photosynthesis. Magnesium is also a part of our body (bones, cartilage, etc.). Alloys of magnesium are also used for aircraft manufacturing.
Calcium: an essential constituent of our body, like in bones and teeth. Calcium compounds have historically been used for construction, including marble, limestone, etc. Calcium is a key constituent of the construction industry in the form of lime.
Strontium: used in fireworks and the sugar industry.
Barium: barium salts have industrial applications in the medical industry, fireworks manufacturing, and paint industry.
Radium: very few applications due to its radioactivity. It was formerly used in watches.
Hope this helps.
