Assertion: Germanium is a rare element found in nature.
Reason: Germanium is not commonly used in industrial applications due to its scarcity.
Both Assertion and Reason are true, and the Reason is the correct explanation of the Assertion.
Both Assertion and Reason are true, but the Reason is NOT the correct explanation of the Assertion.
Assertion is true, but the Reason is false.
Assertion is false, but the Reason is true.
The assertion "Germanium is a rare element found in nature" is true. Germanium is a metalloid element and is relatively rare in the Earth's crust, with an abundance of around 1.6 ppm. It is mainly obtained from the processing of sphalerite ore, which is a zinc sulfide mineral that contains small amounts of germanium.
The reason "Germanium is not commonly used in industrial applications due to its scarcity" is partially true, but it is not the only reason for its limited use. While germanium has some unique properties that make it useful in certain electronic applications, it is also more expensive and less abundant than other elements such as silicon. As a result, germanium is generally only used in specialized applications where its properties are particularly beneficial, such as in infrared optics and solar cells.
Therefore, while scarcity is one of the reasons why germanium is not commonly used in industrial applications, it is not the only factor.
