Question

Phosphorus and sulphur are examples of non-metals as they are:​

• A. lustrous and malleable ​
• B. non-lustrous and malleable​
• C. lustrous and non-malleable​
• D. non-lustrous and non-malleable​

Answer 1

The correct option is D non-lustrous and non-malleable​

Lustre: The ability of a material to shine.​

Malleability: The property of a material by which it can be pressed or rolled into thin sheets.​

​If we take the example of phosphorus present in matchstick head, we can observe that it is not shiny, hence non-lustrous.​

Similarly, sulphur is also not shiny in appearance, hence non-lustrous.​

Moreover, sulphur and phosphorus break to form powder when they are struck. Hence, they are non-malleable​. Therefore, sulphur and phosphorus are examples of non-metals​.
