Common Examples:
* Calcium carbonate (CaCO3): Found in limestone, chalk, and seashells.
* Magnesium oxide (MgO): Used in antacids and as a fire retardant.
* Barium sulfate (BaSO4): Used as a contrast agent in medical imaging.
* Strontium chloride (SrCl2): Used in fireworks to produce red color.
Other examples:
* Magnesium chloride (MgCl2): Found in seawater and used in de-icing agents.
* Calcium hydroxide (Ca(OH)2): Known as slaked lime, used in construction.
* Strontium hydroxide (Sr(OH)2): Used in sugar refining.
* Beryllium oxide (BeO): Used in electronics and ceramics.
Key Points:
* Alkaline earth metals are found in Group 2 of the periodic table (elements like Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium).
* They tend to form compounds with a +2 charge.
* These compounds are often found in nature and have various industrial and biological applications.
