which of the two possess lustre metals and nonmetals
Answers
Answer:
Explanation:
1. DIAMOND
Because of heat conduction, Diamonds are cold to the feel at or below room temperature. ... The luster of Diamond is excellent. Diamond exhibits great "fire" and brilliance, which gives it a shiny, freshly polished look. Rough Diamonds exhibit a greasy luster, but proper cutting give them a powerful adamantine luster.
2.Graphite
It contains dislocalised electrons ( free electrons) moving freely and causing reflection of light falling on them making it lustrous. It is a specular reflection.
3.Iodine
Metals are lustrous, ductile, and conductive of heat and electricity. ... Iodine is in fact a metalloid and not a non-metal, metalloids exhibit the properties of both metals and nonmetals partially, so that is the reason for iodines both metallic and non-metallic properties.Another example is silicon.
