• A. It is a brown powder
• B. It is a good conductor of electricity at low temperature.
• C. More reactive than crystalline silicon
• D. When heated in air, it oxidises at surface level and catches fire

Answer 1

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

The correct options are
A It is a brown powder
C More reactive than crystalline silicon
D When heated in air, it oxidises at surface level and catches fire

Amorphous silicon is a brown powder.It does not conduct electricity at low temperature and is more reactive than crystalline silicon.When heated in air, it oxidises at surface level and catches fire.
