Metals
Those elements which form ions by losing electrons are called metals.
Physical properties of metals
LUSTRE MALLEABILITY
CONDUCTIVITY HIGH MP AND BP
DENSITY SOLID STATE
DUCTILITY SONOROUS
“Bahut Jaroori Table”
- Prashant Bhaiya
Properties Description/Defination
Metals have a shiny appearance, known as metallic lustre, which is due
Lustre
to the reflection of light from their surface.
Metals can be hammered or rolled into thin sheets without breaking.
Malleability
This property is known as malleability.
Metals are excellent conductor of heat and electricity. Silver and
Conductivity copper are particularly good electrical conductors, which is why they
are widely used in electrical circuits.
Metals can be drawn into thin wires. This property is called ductility.
Ductility Copper and aluminum are common examples, often used for electrical
wiring.
Most metals have high melting and boiling points due to the strong
High Melting and
bonding between their atoms. For example, iron and tungsten have very
Boiling Points
high melting points.
Most metals are solid at room temperature, with the exception of
Solid State
mercury, which is liquid.
Metals typically have high density, meaning they are heavy for their
Density
size.
Metals produce a ringing sound when struck, a
Sonorous property known as sonority. This is why metals like iron and
brass are used in making bells and musical instruments.
