Question : Which actinide, discovered by Glenn T. Seaborg in 1940, is used as a heat source for sensitive electrical components in satellites as well as a power source for satellites?
Option 1: Curium
Option 2: Plutonium
Option 3: Nobelium
Option 4: Americium
Correct Answer: Plutonium
Solution : The correct option is Plutonium.
Plutonium-238, an Actinide discovered by Glenn T. Seaborg in 1940, is utilised as both a power source and a heat source for delicate electrical components in spacecraft. With thermoelectric generators, the heat generated during the radioactive breakdown of Pu-238 can be used to generate electricity. This makes it a crucial isotope for space missions where stable, long-lasting power supplies are necessary.
