DIFFERENTIATE BETWEEN PHYSICAL PROPERTIES OF METALS WITH REFERENCE TO MALLEABILITY ...
Answers
Answer:
Metals Non-metals
Metals have lustre. Mercury and gallium are an exception. Non-metals do not have lustre, Iodine and diamond are exceptions.
Metals are solids at room temperature. Mercury is an exception being liquid. Non-metals are either solid or gaseous. Bromine is an exception being in a liquid state.
Metals generally possess the property of hardness. Non-metals do not possess the property of hardness.
They are ductile and malleable. They are non-ductile and malleable.
Metals are good conductors of heat and electricity. Non-metals are bad conductors of heat and electricity except graphite
Key Differences Between Metals and Non-Metals
Metals are considered to be electropositive in nature due to their ability to donate electrons. Whereas non-metals are electronegative as they generally accept electrons.
Metals are generally found in solid-state but non-metals exist in all the 3 states of matter i.e., solid, liquid and gas.
Metals shows the property of malleability while non-metals are non-malleable.
Metals are generally those substances that have a shiny surface and thus are lustrous. Whereas non-metals have non-shiny appearance and thus falls under the category of non-lustrous substances.
The bond formed between metals is said to be metallic bonding. While the bond formed between two non-metals is a covalent bond.
Metal possesses high tensile strength as there exists strong attraction between molecules. However, due to weak intermolecular forces, the tensile strength of non-metals is low.
Metals holds the left side position on the periodic table. But non-metals are usually found on the right side in the periodic table.
Metals exhibit high melting and boiling point except mercury. As against the melting and boiling point of non-metals are generally low except carbon and silicon.
Metals show the property of ductility as can be easily drawn into wires on applying force. However, non-metals are not ductile but carbon is a non-metal that exhibits ductility.
Usually, metals are referred as cations while non-metals as anions.
Metals are said to be good reducing-agents. But non-metals are referred as good oxidizing-agent.
Metals possess very high density in comparison to non-metals.
