Lustrous Non-Metal. Metals with a shiny appearance are referred to as lustrous. Metallic lustre refers to the gleaming appearance of metals. Examples of Lustrous Non-Metal. Metals, such as gold, silver, and copper, have the ability to reflect light from their surfaces and can be polished. Non-lustrous metals, such as lead, are an example.
Elements that tend to gain electrons to form anions during chemical reactions are called non-metals. These are electronegative elements. They are non-lustrous, brittle and poor conductors of heat and electricity (except graphite). Non-metals can be gaseous, liquids or solids.

The first nonmetal on the periodic table is hydrogen, which is atomic number 1. Unlike the other nonmetals, it is located on the left side of the periodic table with the alkali metals.
Non-metals are usually poor conductors of heat and electricity. They are non-lustrous; non-sonorous; non-malleable and are coloured. (a) Name a lustrous non-metal. (b) Name a non-metal which exists as a liquid at room temperature. (c) The allotropic form of a non-metal is a good conductor of electricity. Name the allotrope.
Metals such as gold, copper, etc. have property of lustre. Some non-metals are also lustrous in nature, such as iodine, graphite, diamond etc. Hence, the name of a non-metal having the property of lustre is iodine. Iodine is a non-metal whose color is purple black and is present in solid-state.
