Concept Question
How many metallic elements comprise the group known as Rare Earth Elements (REEs) on the periodic table?
17 elements (15 lanthanides plus scandium and yttrium).
Examiner's Trap
The examiner uses patriotic optimism as a distractor in Statement 2, tempting candidates to incorrectly boost India's global mining rank. In Statement 4, the number 13 is likely meant to confuse candidates with the 15 lanthanides.
Core Insight
REEs like Neodymium and Dysprosium are used to create the world's strongest permanent magnets. These magnets are vital for manufacturing the highly efficient, miniaturized motors and actuators necessary for precise robotics, EV engines, and the cooling systems of massive AI data centers.
