The correct option is

C

1 and 4

Physical Properties Of Nonmetals:

Nonmetals cannot be hammered into thin sheets. It means they don’t possess the property of malleability. Instead they are brittle as they break down into pieces on hammering.

Nonmetals are not ductile. They cannot be drawn into wires.

Nonmetals are a poor conductor of heat and electricity.

Nonmetals are not lustrous which means they are not shiny. Instead dull in appearance.

Nonmetals have low tensile strength. It means they cannot hold heavy weights.

Nonmetals are not sonorous. It means when we strike them, they do not make any sound.

Nonmetals are soft. It means they can be cut by knife easily.

Properties of Metals

Gold, aluminium, iron and magnesium etc. are metals. They show following properties –

Physical Properties of Metals:

Metals can be hammered into thin sheets. It means they possess the property of malleability.

Metals are ductile. They can be drawn into wires.

Metals are a good conductor of heat and electricity.

Metals are lustrous which means they have a shiny appearance.

Metals have high tensile strength. It means they can hold heavy weights.

Metals are sonorous. It means when we strike them, they make a ringing sound.

Metals are hard. It means they cannot be cut easily.

  • Non-metals do not possess the property of malleability and ductility.
  • Non-metals are brittle.
  • Metals can produce ringing sounds and this property is called sonority.
  • Metals have high melting and boiling points.

Statements 2 and 3 are correct. Statements 1 and 4 are incorrect.
Option C is correct.
