Answer:
Uses of alkaline earth metals
Some important uses of alkaline earth metals are:
1. Be is used in the manufacture of alloys. Cu-Be alloys are used in the preparation of high strength springs.
2. Mg is used to prepare alloys with Al, Zn, Mn and Sn. Mg-Al alloys are used in construction of aircrafts.
3. Ca is used in the extraction of metals from their oxide.
4. Radium salt are used in radiotherapy. e.g., treatment of cancer.
Uses of alkali metals
Lithium, sodium, and potassium have many applications, while rubidium and caesium are very useful in academic contexts but do not have many
applications.
Lithium is often used in batteries, and lithium oxide can help process silica.
Lithium can also be used to make lubricating greases, air treatment, and aluminum production.
Pure sodium has many applications, including use in sodium-vapor lamps which produce very efficient light .
Potassium has a vital rolel in biological system. KCl used as a fertilizer while KOH is used in the manufacture of soap.
Caesium is used making photoelectric cells
Group 1 elements are called alkali metal and group 2 elements are called alkaline earth metal.
Some uses of alkaline earth metals of group 2 metals are as follows-
- 1. Beryllium is used in the manufacture of alloys.
- 2. My or Magnesium is used to prepare alloys.
- 3. Ca is widely used in the extraction of metals from their oxide.
- 4. Radium salt is used in radiotherapy like in the treatment of cancer.
Uses of alkali metals or group 1 elements are as follows-
- Li is used in batteries.
- Lithium oxide can help process silica.
- Lithium is used to make lubricating greases.
- Sodium is used in sodium-vapour lamps.
- KCl is used as a fertilizer and KOH is used in the manufacture of soap.
