In the periodic table, metalloids are found:
A. Only in group 18
B. Along the zigzag line separating metals and non-metals
C. Only in the f-block
D. In the s-block
Answer: Option B
Solution (By JKExamLibrary)
Metalloids (B, Si, Ge, As, Sb, Te) are located along the staircase line on the right side of the p-block, dividing metals from non-metals. They exhibit intermediate properties: semiconductors, brittle, can form alloys. They are in groups 13-17. The s-block contains reactive metals. Group 18 contains noble gases. f-block contains lanthanides and actinides.
