Question

Name a non-metal that has lustre.

Answer 1

Hint:
We know that lustrous is generally a property of metals. Lustre means shining. Non-metals are the elements present in right side of the periodic table, such as, oxygen, nitrogen etc.

Complete step-by-step answer:
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.

Additional Information:
Iodine is a non-metal whose color is purple black and is present in solid-state. It is the least reactive among halogens but still forms many compounds with other elements. On heating, it sublimes easily giving a purple vapor. In some solvents, such as ${\rm{CC}}{{\rm{l}}_{\rm{4}}}$, it is soluble but in water, it is only slightly soluble. The use of iodine in medicine is in the form of tincture and iodoform. It is also used in certain drug preparation, manufacture of ink used in painting and dyes. It is used in photography also. It is also an ingredient of tablets for purifying water which is used to purify drinking water. Iodine is added to almost any form of salt used. It is a component of bread, seafood, and oceanic plants.
Naturally, iodine is found in the water of oceans and seas and it is stored in its tissues of some sea fish and aquatic plants. Iodine is very important for our body. The deficiency of iodine in the body causes goitre.

Note:
Metals have the property lustre because of presence of free electrons. The free movement of electrons in the metal causes reflection of incident light which is why they shine.
