chemical properties of metals and non metals please give me the correct answer please write it on a paper and send me image

Answer:
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 e.g. Iron.
Metals are good conductors of heat and electricity. Lead is an exception.
Generally, metals are in a solid state at room temperature. Except for Mercury. Mercury is in a liquid state.
Many metals produce metal oxide by burning in the oxygen of the air. Highly reactive metals react violently when they’re burnt in oxygen.
Metals like sodium and potassium are stored in oil as they react with air in seconds. They’re highly reactive metals.
Less reactive metals like gold, silver, platinum, etc do not tarnish easily. They stay shiny and lustrous.
Metals produce metal oxide and hydrogen gas while reacting with water.
Soluble metal oxides dissolve in water and create metal hydroxide.
Not all metals react with water. However, highly reactive metals like sodium and potassium react with water violently and an exothermic reaction takes places where the hydrogen immediately catches fire.
Salt and hydrogen are produced when a metal reacts with an acid.
Generally, a metal displaces a less reactive metal in a metal salt solution.
Chemical Properties of Non-Metals
1. Reaction with Water
A non-metal does not react with water but it is usually very reactive in air, which is why some of them are stored in water. For example, one of the highly reactive non-metals is phosphorus and it catches fire when exposed to air that is why it is stored in water to prevent its contact with atmospheric oxygen.
2. Reaction with Acids
None of the non-metals is known to react with acids.
3. Reaction with Bases
The reaction between non-metals and bases is a very complex one. The reaction of chlorine with bases like sodium hydroxide gives products like sodium hypochlorite, sodium chloride as well as water.
4. Reaction with Oxygen
Oxides of non-metals are formed when it reacts with oxygen. The oxides of non-metals are acidic or neutral in nature.
When sulphur reacts with oxygen, we get sulphur dioxide.
S + O2 → SO2
When sulphur dioxide reacts with water it forms sulphurous acid
