Question

. A molecule is the pure basic substance that cannot be split into two or more simpler substances by chemical methods.

• A. True
• B. False

Answer 1

The correct option is B False

Molecule:

• Some atoms do not exist alone, they combine together to form molecules.
• A group of atoms is called a molecule.
• A molecule is a pure substance and can be split into two or more substances by chemical methods.
• For example when an electric current is passed through water molecules (${\mathrm{H}}_2\mathrm{O}$), it splits into hydrogen(${\mathrm{H}}_2$) and (${\mathrm{O}}_2$).

Concluding statement: A molecule is a pure basic substance that can be split into two or more simpler substances by chemical methods. Hence given statement is false.
