Write the physical and chemical properties of metals and non metals.

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 $4-7$.

Physical properties of metals-

• Metal is a good conductor of heat and electricity
• At room temperature, it is in solid form except mercury.
• They are opaque and ductile.

Chemical properties of metals-

• They have low electronegativities.
• They can lose electrons.
• They are good reducing agents.
