morphous silicon
It is a brown powder
It does not conduct electricity at low
temperatures.
It is more reactive than crystalline
silicon
When heated in air, it oxidizes at the
surface level & catches fire
Crystalline silicon
It is a dark grey crystalline solid and
rough. It resembles the structure of
diamond
Slightly conducts electricity
It is less reactive than amorphous
silicon
It does not burn in air even when
heated
