- Metals occur in the solid state.
- Metals are malleable in nature.
- Metals are ductile.
- Metals conduct heat and electricity.
There are two types of elements, metals and non-metals. Your books, clothes, pencil, water bottle, bag, table, door are all examples of non-metals.
The periodic table has an arrangement of elements based on their chemical properties. Out of 92 elements that are known to be found naturally, 70 are metals and 22 are non-metals. The left-hand side of the periodic table has metals separated from non-metals by a zigzag line that starts from Carbon.
The row just to the left of the non-metal elements is known as semi-metals or metalloids. For example, elements such as aluminum, gold, and silver can be beaten into thin sheets. The metal’s heat and electricity can be passed through it. The lustrous nature of metals is due to the light hitting its surface.
The metals are hard and strong. They produce a sound when rung or hit.
The metals in objects are not transparent or translucent. Non-metal elements don’t have the same properties as metals. There are less non-metals on the periodic table than there are metals. The non-metals include hydrogen, carbon, nitrogen, phosphorus, oxygen, sulphur, selenium, and all the halogens.
Non-metals are poor conductors of heat and electricity because they don’t lose electrons. They can be in either liquids or gases at room temperature. Non-metals are more likely to accept or gain electrons.
The non-metal elements are good oxidizers. The physical properties of metals and non-metals were compared.
Non-metals can’t give electrons to hydrogen in water. Zn and Al form amphoteric oxides, which show the properties of both acidic and basic oxides.
Oxygen and non-metals form oxides. H2 is not released when metals react with acid.
There is no reaction with acids to release H2 gas. Non-metals have no loss of electrons to give it to acids. It is done for carbonate ores CaCO3 CaO + CO2(g) in the absence of oxygen. It is done for sulphide ores when metal oxide is formed and SO2 gas is released.
The equation comes from the fact that metals are good conductors of electricity. Non-metals do not lose electrons to give it a hydrogen ion.
The ores are heated in the absence of oxygen and metal oxide is formed. In roasting metal oxide is obtained.
What are the 11 physical properties of metals?
- Metals can be hammered into thin sheets.
- Metals are ductile.
- Metals are a good conductor of heat and electricity.
- Metals are lustrous which means they have a shiny appearance.
- Metals have high tensile strength.
- Metals are sonorous.
- Metals are hard.
The properties of elements distinguish them. Those elements which are good conductors of heat and electricity are found in metals.
Nonmetals are not good conductors of heat and electricity. They don’t have the property of malleability. Nonmetals are not good conductors of heat and electricity.
Aqueous solution of nonmetal oxide turns blue litmus paper into red. Nonmetals do not produce hydrogen gas.
It makes up for the displacement of iodine in the compounds. A good conductor of heat and electricity is metal.
The metals have a shiny appearance. When magnesium reacts with oxygen it forms magnesium oxide. Aqueous solution of metal oxide turns red paper into litmus. The physical and chemical properties of metals and nonmetals are differentiating.
Here, we show the difference between metal and nonmetal in tabular form with exceptions for your better understanding. A good conductor of electricity. Do not react with strong bases. Nonmetal oxides turn litmus paper red.
Nonmetal oxides form acids. The topic of theProperties of Metals and Nonmetals is over.

What are the main properties of metals?
- high melting points.
- good conductors of electricity.
- good conductors of heat.
- high density.
Malleable substances can be bent or hammered into shape without shattering, while brittle substances can shatter when bent or hit. A metal can be drawn out into thin wires.
What are the 4 main properties of metals?
Good conductors of heat and electricity can be found in metals. There will be a new year in 2021.
