Gypsum is an industrially important mineral. It is the primary ingredient of plaster-of-Paris, which is finely ground Gypsum, and it is used in the production of cement. It is also the main component of sheet rock. It is used as a flux for creating earthenware, and can be used as a fertilizer.
Alkali Metals are rarely found in pure form, and if they are they are normally stored under oil, because they react with water and water vapor in the air very violently.They â¦ explode if placed in water because they have one electron in their outer energy level and they want to give it away so badly.lkali Metals are rarely found in pure form, and if they are they are normally stored under oil, because they react with water and water vapor in the air very violently.
The alkali metals, halogens and noble gases are three important groups in the periodic table. The alkali metals are soft, reactive metals. They react vigorously with water and become more reactive as you go down the group.The halogens are reactive non-metals.They become darker as you go down the group.he alkali metals have the following properties in common: 1  they have low melting and boiling points compared to most other metals. 2  they are very soft and can be cut easily with a knife. 3  they have low densities (lithium, sodium and potassium will float on water).
