Correct Answer - Option 2 : Ductility
The property of metal in which it can be drawn into thin wires is ductility.
Explanation:
Metal:
- Metal is such a kind of electropositive element that usually has a shiny surface.
-
It is generally good conductors of electricity & heat.
-
Metal can be fused, melted, or hammered into thin sheets.
- Out of 118 elements, the first 94 occur naturally on Earth, and the remaining 24 are synthetic elements.
- All metals exist in a solid state at room temperature.
-
Mercury is the only metal that exists in the liquid state at room temperature.
- Metals are the elements that have loosely bound electrons they can give up easily.
- They generally lie on the left side of the periodic table.
Metals have the following properties:
-
Conductivity:
- The property to carry heat and electricity is called conductivity.
-
Metals are good conductors of heat and electricity, they are used in to make electrical wires and cooking utensils.
- Metals can absorb heat very easily.
-
Ductility:
- The property of metal to be drawn into wires is called ductility.
- Metals such as copper are used to make wires.
-
Sonority:
- Metals make sounds when they hit a solid surface or hit each other. This property of metals is known as sonority.
- For their sonorous nature, metals are used in bell, etc.
-
Malleability:
-
The property of metals to be beaten into thin sheets is known as malleability.
- Metals such as gold, aluminium are highly malleable and can be beaten into thin sheets.
- They are opaque and are denser than other elemental substances.
Physical Properties of nonmetals :
- Density: Nonmetals have low densities.
- Lustre: Nonmetals do not have lustre, except diamond and iodine crystals.
- Brittleness: Solid nonmetals are brittle. Some nonmetals are soft. Diamond (an allotrope of carbon) is an exception, which is the hardest natural substance.
- Ductility & Malleability: Non-metals are neither ductile nor malleable.
- Conduction of Heat & Electricity: Non-metals are bad conductors of heat and electricity except graphite.
- Physical State: At ordinary temperature nonmetals occur as solids, liquids, and gases.
