Answer 1

Physical properties of metals:
1. Lustre (shine): Metals usually have a high lustre which means they are shiny.
2. Hardness: Metals are usually hard but not brittle which means metals cannot be broken easily.
Exceptions: Sodium,Potassium.
3. Boiling and melting point: The boiling and melting points of metals are high which means metals need high temperature to boil or melt.
Exceptions:Sodium,potassium.
4. Conduction of heat and electricity: Metals are good conductors of heat and electricity which means heat and electricity can pass through metals easily.
5. Density: Metals have high density.
6. Ductility: Metals are ductile. The ability of a metal to be drawn into a thin wire is called ductility.
7. Malleability: Metals are malleable. The ability of a metal to be beaten into a sheet is called malleability.
8. Sonorous: Metals are sonorous which means they are capable of producing sound.

Answer 2

heya!!☺

here is your answer ⤵️

the physical properties of metal are :

➡️ LUSTER: metals have a shinning surface called luster. they have a quality of reflecting light from their surface and they can be polished.
examples: metals like siliver, copper, show this property.

➡️ HARDNESS: metals are generally hard e.g. iron, cobalt, nickel. there are few exceptions to this. sodium and potassium are soft and they can be cut with a knife.

➡️ MELTING AND BOILING POINT: metals usually have high melting point and boiling point . for example, iron, cobalt, and nickel have high melting and boiling point. TUNGSTEN has the highest melting point. most of the alkali metals have low melting and boiling point.

➡️ CONDUCTION: metals are good conductors of heat and electricity because they have free electrons. siliver and copper are two best conductors. and lead and bismuth are poor conductors of heat and electricity.

➡️ DENSITY : metals have a high density and they are heavy . Iridium and osmium have the highest densities while lithium has the lowest density.

➡️ DUCTILITY : metals can be drawn into thin wires. this property is called ductility .

➡️ MALLEABILITY: metals can be beaten into thin sheets. this property is called malleability. due to this property, metals can be rolled into sheets e.g. aluminum, copper, zinc can be beaten into sheets.

➡️ SONOROUS: the metals which give ringing sound is called sonorous.
