Which of the following elements is classified as a metalloid?
Germanium
Gallium
Gold
Gadolinium
Germanium
Germanium is classified as a metalloid because its physical and chemical properties lie intermediate between those of metals and non-metals. It possesses a metallic lustre but is brittle and acts as a semiconductor.

Think of a metalloid like an amphibian that can live both in water and on land; it has characteristics of both worlds rather than fitting purely into one category.

Metalloids, or semimetals, are situated along the diagonal dividing line between metals and non-metals on the periodic table. They typically have valence electrons that allow them to conduct electricity under specific conditions, making them essential materials in semiconductor electronics.
Germanium is a lustrous, hard, grayish-white metalloid in the carbon group.
Gallium and Gold are classified as metals.
Gadolinium is an inner transition metal belonging to the lanthanide series.
High electron mobility makes it useful for high-speed electronic devices.
Sensitive to temperature changes, limiting performance at high temperatures compared to silicon.
Manufacturing of semiconductor devices and transistors
Fiber optics and infrared optics
Option A (Germanium) is a metalloid.
Option B (Gallium) is a post-transition metal.
Option C (Gold) is a transition metal.
Option D (Gadolinium) is a rare-earth metal (lanthanide).
A is correct тАФ Germanium is a metalloid possessing properties intermediate between metals and non-metals.
Make sure to memorize the standard metalloids on the periodic table (B, Si, Ge, As, Sb, Te, Po) as they frequently appear in railway and engineering competitive exams.
