Question

Sulphur and carbon are

• A. metals
• B. non-metals
• C. metalloids
• D. noble gases

Answer 1

The correct option is B

non-metals

Sulphur and carbon are - (B.) non-metals.

Explanation for incorrect options :

• Metals are electropositive and lustrous. They also exhibit the properties of ductility and malleability which aren't shown by sulphur and carbon.
• Metalloids are brittle like non-metals but they appear lustrous like metals. Sulphur and Carbon are not lustrous, so they are not metalloids.
• Noble gases are inert and stable and they are unreactive too. Sulphur and carbon whereas are not unreactive.

Explanation for correct option:

• Sulphur (S) and Carbon (C) are electronegative elements and both are non-lustrous and brittle hence, they exhibit the properties of non-metals. Hence, both Sulphur and Carbon are non-metals.

Hence, option B is correct.
