• A. Lustre
• B. Brittle
• C. Electronegativity value is near 2
• D. can form alloys
• E. Amorphous

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A Lustre
B Brittle
C Electronegativity value is near 2
D can form alloys

Metalloids

Elements on both sides of the zigzag line have properties of both metals and nonmetals. These elements are called metalloids.

Physical properties of metalloids:

• Solids
• Can be shiny or dull
• Ductile
• Malleable
• Conduct heat and electricity better than nonmetals but not as well as metals
• can form alloys
  
• Electronegativity value near 2
  
• Brittle
  
• Hence options A,B,C & D are correct.
