Which metal is lustrous?
Luster: Metals have the quality of reflecting light from its surface and can be polished e.g., gold, silver and copper….
Is Diamond a lustrous non metal?
So, diamond is essentially non-metal. Hence, the correct answer we are looking for is both iodine and diamond are lustrous non-metals. So, the answer is D. Note: Diamond as discussed has the highest non-metallic lustre; this is also known as “adamantine”.
