Physical properties of non metals-
non-metals are poor conductor of heat and electricity
At room temperature, they may be solids liquids or gases.
They are transparent and non ductile.
Chemical properties of non metals-
They can easily gain electrons
They are high electronegative elements.
The number of electrons in the outer shell is generally 4−7.
