With reference to the Rare Earth Metals, consider the following statem...
The correct answer is option 'C': Both 1 and 2.
Explanation:
1. These minerals have unique magnetic, luminescent, and electrochemical properties:
- Rare Earth Metals (REMs) are a group of elements that exhibit unique properties such as magnetic, luminescent, and electrochemical properties.
- These elements are known for their high magnetic strength, which makes them essential in the production of magnets used in various applications like electric motors, speakers, and computer hard drives.
- Some rare earth elements also possess luminescent properties, meaning they can emit light when exposed to certain conditions. This property is utilized in the production of lighting and display technologies, such as LED lights and screens.
- Additionally, rare earth metals have electrochemical properties, making them crucial for the manufacturing of batteries, fuel cells, and other energy storage devices.
2. They are a set of seventeen metallic elements:
- Rare Earth Metals consist of a group of seventeen chemical elements, which are often divided into two categories: Light Rare Earth Metals (LREEs) and Heavy Rare Earth Metals (HREEs).
- LREEs include elements such as lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), and samarium (Sm), among others.
- HREEs include elements such as europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), and yttrium (Y), among others.
- These elements are generally referred to as "rare" because they are not commonly found in concentrated forms in the Earth's crust. However, they are actually more abundant than some other elements, such as gold or platinum.
- Rare earth elements are usually found in combination with other minerals and are extracted through complex processes.
In conclusion, both statements are correct. Rare Earth Metals possess unique magnetic, luminescent, and electrochemical properties, and they are a set of seventeen metallic elements. These elements have various industrial applications, ranging from electronics and renewable energy to defense and healthcare.
