Question

what is non metal , mention it's properties​

Answer 1

Answer:

DEFINITION OF NON-METALS

A non-metal is typically brittle when solid and usually has poor thermal conductivity and electrical conductivity. Chemically, nonmetals tend to have relatively high ionization energy, electron affinity, and electronegativity. They gain or share electrons when they react with other elements and chemical compounds.

PROPERTIES OF NON-METALS

They are generally poor conductors of heat and electricity.

Solid non-metals are generally brittle, with little or no metallic luster.

Most non-metals have the ability to gain electrons easily.

Non-metals display a wide range of chemical properties and reactivities.

Answer 2

Answer:

NON-METAL

DEFINATION :-

An element or a substance that is not a metal, said to be a non-metal.

EXAMPLES OF NON-METALS-

NON-METALS THAT EXIST IN SOLID STATE :-

• Carbon
• Sulphur
• Phosphorus
• Iodine
• Selenium

NON-METALS THAT EXIST IN LIQUID STATE :-

• Bromine

NON-METALS THAT EXIST IN GASEOUS STATE :-

• Chlorine
• Oxygen
• Nitrogen
• Helium
• Argon
• Zenon
• Neon

PROPERTIES :-

• Non-metals may be solid, liquid or gaseous at room temperature.
• They generally have low melting as well as boiling points.
• They generally have a low density.
• They are not hard and easy to break. ( except Diamond )
• They generally have a dull appearance.
• They are non-malleable and non-ductile.
• They do not have tensile strength. ( except Carbon Fibre )
• They are non-conductors or insulators. ( except Graphite )
• They are not sonorous. Hence, don't produce any sound when beaten with hammer .
