Question

metal and nonmetal chemical properties​

Answer 1

Answer:

CHEMICAL PROPERTY OF METAL-

• Usually have 1- 3 electrons in their outer shell
• Lose their Valence electron easily
• Form oxides that are basic
• Are good reducing agent
• Have lower electronegativities.

CHEMICAL PROPERTY OF NON METAL -

• Usually have 4 - 8 electrons in their outer shell
• Gain or share valence electron easily
• Form oxides that are acidic
• Are good oxidizing agent
• Have higher electronegativities.

Answer 2

Answer:

Chemical properties of metal:-

• The density of metals is usually high.
• Metals are malleable and ductile.
• Metals form an alloy with other metals or non metals.
• Some metals react with air and corrode. For example :- Iron.
• Metals are in a solid state at room temperature. Expect for Mercury. Mercury is in liquid state.
• Metals produce metal oxide and hydrogen gas while reacting with water.
• Soluble metal oxide dissolve in water and create metal hydroxide.

Chemical properties of non metal :-

• Non metals are poor conductor of heat and electricity.
• Non metals are not malleable and ductile.
• They react with other non metals in high temperature. But not react witj air at room temperature.
• They react with metals more than non metals.
• White phoporous is only non metal that react with air to form its oxides by burning.
• They do not form alloy. However, non metals like carbon, silicon.
• Different non metals have different reaction. They have a low density.
