Question

State three reasons (of which at least one must be chemical) for believing that sulphur is a nonmetal.

Answer 1

1. Sulphur is not lustrous, which shows that it is a non-metal.
2. Sulphur is a non-sonorous material, which shows that it is a non-metal.
3. Sulphur reacts with oxygen to form sulphur dioxide, which is acidic in nature. This shows that it is a non-metal.
