Lustrous non metal:
- Lustrous means shiny or reflective, so we are looking for a non-metal substance that has a shiny appearance.
- Let's evaluate each option to determine which one fits the criteria.
A: Sulphur:
- Sulphur is a non-metal element.
- However, sulphur is not lustrous. It has a dull appearance and is not shiny or reflective.
B: Iodine:
- Iodine is a non-metal element.
- Iodine has a shiny appearance and is lustrous.
- Therefore, iodine is a lustrous non-metal.
C: Diamond:
- Diamond is a form of carbon and is classified as a non-metal.
- It is considered the hardest naturally occurring substance and has a high refractive index, giving it a shiny appearance.
- Therefore, diamond is a lustrous non-metal.
D: Phosphorus:
- Phosphorus is a non-metal element.
- However, phosphorus is not lustrous. It has a waxy appearance and is not shiny or reflective.
Conclusion:
- Among the given options, both iodine and diamond are lustrous non-metals.
- However, the correct answer is Iodine (Option B) as it is the only non-metal that is consistently lustrous and does not require specific conditions (like high pressure) for its lustrous appearance.
