Question

Iron and sulphur both are elements whereas iron sulphide is a compound, explain.

Answer 1

• Iron and sulfur are elements whose properties are completely different from the properties of iron sulphide $\left(\mathrm{FeS}\right)$.
• Iron and sulfur chemically combine together in a fixed ratio of their weight to form a completely new substance known as Iron sulphide $\left(\mathrm{FeS}\right)$.
• So, Iron sulfide $\left(\mathrm{FeS}\right)$ is a compound.
• The element is the fundamental unit of matter that cannot be broken down into simpler substances but can be combined to form new substances.
• Compounds are chemical substances made up of two or more elements that are chemically bound together in a fixed ratio.
