Question

The metal that has very low melting point and its periodic position is closer to a metalloid is

• A. Al
• B. Ga
• C. Se
• D. ln

Answer 1

The Correct Option is B

The question asks which metal has a low melting point and is positioned closer to a metalloid in the periodic table. Let's analyze the options provided:

1. Aluminium (Al): Aluminium is a metal with a relatively high melting point of about 660.3°C. It is located in Group 13. Although it is close to metalloids like silicon, it does not have a very low melting point.
2. Gallium (Ga): Gallium is a metal with an extraordinarily low melting point of about 29.76°C. It is in Group 13, right next to metalloids such as germanium. Because of its low melting point and position near metalloids, Gallium matches the given conditions of the question.
3. Selenium (Se): Selenium is a non-metal located in Group 16. It is near metalloids, but being a non-metal, it is not relevant to this question about metals.
4. Indium (In): Indium is a metal in Group 13 with a melting point of about 156.6°C. Although it is relatively close to metalloids, its melting point is not as low as that of Gallium.

Based on this analysis, the metal that has a very low melting point and its periodic position is closer to a metalloid is Gallium (Ga).

Therefore, the correct answer is Gallium (Ga).
