What is luster? Give an example.

Answer 1

Hint:Luster is a property of an element that makes it interesting and exciting. This property is only shown the elements that are on the left side of the periodic table, i.e., metals.

Complete step-by-step answer:We know that there are many elements in the universe each element has many properties by which can define the element. There are many properties like malleability, ductility, luster, conductivity, volume, density, the formation of bonds, state of matter, etc.
On the basis of the properties, a periodic table is developed, in which the metal is on the left side while the non-metals are on the right side.
Luster is a property that defines the shining ability of the element. Luster happens when the light from a source falls on the surface of the rock, element, or any substance and there is a reflection of light that causes a shining and glowing appearance. Luster makes the element interesting and exciting. This property is only shown the elements that are on the left side of the periodic table, i.e., metals. Usually, non-metals do not have this property.
Gold is an element that has a very good property of luster. Other examples of elements that have the property of luster are copper, aluminium, platinum, silver, etc all these are metals. An example of a non-metal which shows luster is diamond (an allotrope of carbon atom).

Note:When the metals in minerals have great luster but due to weathering and corrosion of the rocks, the luster of the metals decreases. Due to this property of luster gold, silver, platinum, and diamond are used as jewelry.
