Question

A substance which is made up of atoms of two or more elements combined chemically is called______________

Answer 1

Compound:

• A compound is a substance that results from a combination of two or more different chemical elements, in such a way that the atoms of the different elements are held together by chemical bonds that are difficult to break.
• Examples: Sodium chloride(NaCl), Distilled water(H₂O).
• Sodium chloride i.e $\mathrm{NaCl}$ is composed of sodium and chlorine atoms which are different and distilled water i.e ${\mathrm{H}}_2\mathrm{O}$ is composed of two hydrogen atoms and one oxygen atom which are different atoms.

Therefore, A substance that is made up of atoms of two or more elements combined chemically is called a compound.
