Ductility is when a solid material stretches under tensile stress. If ductile, a material may be stretched into a wire. This property is not seen in non-metals.Examples are copper, aluminium and steel.
PHYSICAL STATE OF METAL - DEFINITION
All metals are solid at room temperature .Mercury and gallium are the exceptional case which is present in liquid state in room temperature.
ELECTRICAL CONDUCTIVITY IN METALS - DEFINITION
Electrical conductivity is the measure of a material's ability to accommodate the transport of an electric charge.Examples of metals are brass, copper etc.
Examples of non-metals are graphite.
LUSTRE - DEFINITION
The state or quality of shining by reflecting light; glitter, sparkle, sheen or gloss.
Metals are lustrous whereas non-metals have no lustre.
SONORITY - DEFINITION
Since metals produce ringing sounds, they are said to be sonorous.
All metals are sonorous and non-metals are not sonorous.
MALLEABILITY - DEFINITION
Malleability is the ability of a metal to be hammered into thin sheets. When a piece of hot iron is hammered it takes the shape of a sheet. The property is not seen in non-metals.
Example are Gold and silver which are highly malleable.
HARDNESS OF METAL - DEFINITION
Hardness is the measure of resistance of solid towards deformation.
Metals always shows great hardness. Example : iron rod.
DEFINE LUSTRE OF METALS WITH EXAMPLE - DEFINITION
Lustrousness is the property of metal in which they have shiny surface area.
Example : Gold, copper , etc.
HEAT CONDUCTIVITY - DEFINITION
The property of metal to conduct heat is called as heat conductivity of metal.
Metals like aluminum , copper shows this property.
DUCTILITY OF METALS - DEFINITION
The ability of solid materials to deform under tensile stress is called as ductility.
This is often characterized by the material's ability to be stretched into a wire.
Example : copper , aluminum.
MALLEABILITY OF METALS - DEFINITION
Malleability is the ability of a metal to be hammered into thin sheets. Gold and silver are highly malleable. When a piece of hot iron is hammered it takes the shape of a sheet.
PHYSICAL STATE OF ELEMENTS - DEFINITION
Metals are solids at room temperature with the exception of mercury and gallium, which are liquids at room temperature.Most of the non-metals exist in two of the three states of matter at room temperature: gases (oxygen) and solids (carbon). These have no metallic lustre, and do not reflect light.
