(c) sulphur (d) platinum

2. Property of metal to be drawn into wire known as:

(c) lustre (d) tensile strength

3. Property of metal to be beaten into thin sheet is known as:

(a) malleability (b) ductility
(c) lustre (d) tensile strength

Answer 1

Dear Student,
1. Sulphur is the non-metal and other options are metals
2.Ductility:

ductility is the property of metals by which the wires are drawn in thin long wires and are used for many purposes.

for eg:-

the copper wires which are used in homes to conduct electricity sare due to the ductility of copper.

we see gold and silver ornaments in jewellery shops which again shows that gold and silver are ductile.

Gold is the most ductile metal.

1gm of gold can be drawn into a wire running upto 2 km.

3.

Malleability: Malleability is the ability of something to be hammered into sheets without breaking. It is a physical property.
