1. Question
With reference to rare earths minerals, consider the following statements:
1. The rare earths minerals (REM) are a set of seventeen metallic elements.
2. The REMs have unique catalytic, metallurgical, nuclear, electrical, magnetic and luminescent properties.Which of the statements given above are correct?
CorrectAnswer: C
What are REMs?
• The rare earths minerals (REM) are a set of seventeen metallic elements. These include the fifteen lanthanides on the periodic table in addition to scandium and yttrium that show similar physical and chemical properties to the lanthanides.
• The REMs have unique catalytic, metallurgical, nuclear, electrical, magnetic and luminescent properties. While named ‘rare earth’, they are in fact not that rare and are relatively abundant in the Earth’s crust.Strategic importance of REMs:
• They have distinctive electrical, metallurgical, catalytic, nuclear, magnetic and luminescent properties.
• Its usage range from daily use (e.g., lighter flints, glass polishing mediums, car alternators) to high-end technology (lasers, magnets, batteries, fibre-optic telecommunication cables).
• Even futuristic technologies need these REMs (For example high-temperature superconductivity, safe storage and transport of hydrogen for a post-hydrocarbon economy, environmental global warming and energy efficiency issues).
• Due to their unique magnetic, luminescent, and electrochemical properties, they help in technologies perform with reduced weight, reduced emissions, and energy consumption; therefore give them greater efficiency, performance, miniaturization, speed, durability, and thermal stability.IncorrectAnswer: C
