Explanation:Atoms are the smallest particles of elements that can take part in a chemical reaction.Atoms of an element have the same number of protons but may have a different number of electrons or neutrons.Atoms of the same element with different neutrons are called isotopes.An element may have two or more isotopes. For example, oxygen isotopes; oxygen-16, oxygen-17 and oxygen-18.Atoms may have a different number of electrons when they lose or gain an electron(s) to attain a stable configuration.
