Question

what are the characterstics of metals ??​

Answer 1

Answer:

Physical Properties of Metals

Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Other properties include: State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days).

Answer 2

Answer:

Characteristics of metals are:-

• Malleability - The property of a metal to be beaten into thin sheets is known as malleability.
• Ductility - The property of a metal to be twisted into a thin wire is known as ductility.
• Sonorosity - When a metal is banged with a hammer, it produces a ringing sound. This property of metals is sonorosity.
• Thermal & Electrical Conductivity - This property of metals enables them to allow heat and electricity to pass through them.
• Thermal Expansion - When metals are heated, they expand. This property is known as thermal expansion.
• Physical State - All metals, except Mercury (which is a liquid), are solid in their physical state.
• Density - Metals generally have a high density.
• Hardness - Most metals are very hard. They can withstand quite high pressures without getting distorted.
• Lustre - Metals have a shining surface. This is known as metallic lustre.
• Tensile Strength - It is the property due to which are substance can bear a lot of pressure without breaking.
• Melting & Boiling Point - Metals usually have a high melting and boiling point. But one exception is that of Caesium metal. Its melting point is only 28.7°C.
