Introduction
Exploring the Magnificent Realm of Alkaline Earth Metals can prove to be exceptionally fascinating. These metals comprise six elements located in group 2 of the periodic table, namely Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), and Radium (Ra). The article will explain what Alkaline Earth Metals are, their properties and applications.What are Alkaline Earth Metals?
Alkaline Earth Metals are a group of elements that possess specific characteristics that differentiate them from other groups. To be specific, they have two valence electrons (electrons found in the outermost energy level), possess low ionization energies, low electronegativity, have relatively high melting points amongst others.The Characteristics of Alkaline Earth Metals
The Alkaline Earth Metals possess unique chemical and physical properties that give them a place of pride on the periodic table. For example, they are excellent conductors of heat and electricity, possess relatively low densities compared to other heavy metals like Gold and Iron. They also have a characteristic metallic luster and can form alloys via chemical bonding.Melting and Boiling Points
One of the most remarkable features of Alkaline Earth Metals is their high melting and boiling points. Beryllium has the highest melting point, i.e., 1287 °C (2349oF), while Barium has the lowest melting point i.e., 727oC (1340.6oF).It is noteworthy that the higher boiling points of these metals make them ideal for usage in areas that necessitate heat that can corrode or deteriorate other materials. Additionally, their high boiling and melting points also make them suitable for use as structural materials.Density
The density of a material helps determine its overall suitability for specific applications. Alkaline Earth Metals possess relatively low densities compared to other heavy metals like Gold and Iron.For instance, Magnesium is a low-density metal with a density of 1.738 g/cm^3. Calcium has a slightly higher density of 1.54 g/cm^3 while Beryllium has an even higher density of 1.85 g/cm^3. It is important to note that lower densities do not imply low strength.Reactivity
It is to be noted that Alkaline Earth Metals are highly reactive elements that can easily combine with other elements to form compounds. They have a high affinity for oxygen and can rapidly react with it when exposed to air or water.For example, Magnesium reacts with water and oxygen at room temperature, and Strontium ignites when spontaneously exposed to air. These reactions help seal their place as essential elements in applications such as desiccants, fireworks, and other pyrotechnic displays.The Applications of Alkaline Earth Metals
Alkaline Earth Metals are utilized in various industries owing to their unique characteristics. For example, Magnesium finds application in auto parts, metallurgical processes, and the production of electronics.Metallurgy
Metallurgical processes involve the extraction of metals from ores, the refining, and casting of these metals to form alloys. Alkaline Earth Metals play an essential role in metallurgical processes as they contribute greatly to the properties of the materials produced.For example, Magnesium can function as an alloying agent in Aluminum; when combined, it improves Aluminum's tensile and compressive strengths.Medical Applications
Some of the Alkaline Earth Metals (especially Barium) also possess medical applications. In radiology, Barium solutions act as contrast agents that help make images of the digestive system better. Another application involves the usage of Radium-223, a radioisotope of Radium, in the treatment of certain cancers.Conclusion
In conclusion, exploring the world of Alkaline Earth Metals can be an exciting experience. They possess unique physical and chemical properties that make them ideal for a multitude of applications. From metallurgy to medicine, pyrotechnics, among other fields, Alkaline Earth Metals have proved their importance. Therefore, further research and development of these elements must continue to unearth new applications and products.| Alkaline Earth Metal | Melting Point (°C) | Boiling Point (°C) | Density (g/cm³) |
