Matter is composed of tiny particles which may be atoms, molecules or ions. Name the three states of matter. What is the difference: (i) between an atom and an ion, (ii) between an atom and a molecule? Diffusion is evidence for the movement of tiny particles in a liquid or in a gas. Give an example of diffusion. Supply the missing words in the following statement of Boyle's law: 'The _1_ of a certain mass of gas is inversely proportional to its _2_ at constant _3_.

Answer

An atom is a neutral particle that has no charge, while an ion is a charged atom that has either lost or gained electrons. Thus, atoms have an equal number of protons and electrons, whereas ions have an unequal number.

Step 3

(ii) between an atom and a molecule.

Answer

An atom is the smallest unit of an element and is capable of independent existence. A molecule, on the other hand, is formed when two or more atoms bond together and represents the smallest part of a substance that can exist independently.

Step 4

Give an example of diffusion.
