Question

In a compound, the constituent elements are present in a ________.

Answer 1

Compound: A compound is a pure substance in which two or more elements combine chemically in a fixed composition or ratio to give a compound.

• Different elements combine in a fixed ratio to give a compound.
• Example: Water $\left({\mathrm{H}}_2\mathrm{O}\right)$
• In water, elements Hydrogen $\left(\mathrm{H}\right)$ and Oxygen $\left(\mathrm{O}\right)$ have combined in a fixed ratio i.e.; 2 atoms of Hydrogen have combined with one atom of Oxygen. A combination of Hydrogen and Oxygen atoms in the ratio of 2:1 can lead to the formation of water.

Therefore, in a compound, the constituent elements are present in a fixed ratio.
