what is the differenation
non metals
Answers
Answer:
non metals are poor conductor of heat and electricity.
they are not lustrous.
they are not ductile.
they are not sonorous.
they are not rigid.
they are soft.
for eg:- plastic,wood ,paper etc.
Nonmetal, in physics, a substance having a finite activation energy (band gap) for electron conduction. This means that nonmetals display low (insulators) to moderate (semiconductors) bulk electrical conductivities, which increase with increasing temperature, and are subject to dielectric breakdown at high voltages and temperatures. Like metals, nonmetals may occur in the solid, liquid, or gaseous state. However, unlike metals, nonmetals display a wide range of both mechanical and optical properties, ranging from brittle to plastic and from transparent to opaque.
