Some elements exhibiting isotopy include: The mass spectrometry experiment conducted on (isotopic) atoms had given a confirmation to the existence of isotopes. You can read on worked examples of molar mass here.īased on the above explanations, isotopes have the same number of protons (atomic number) but different number of neutrons. The mass number of an atom is defined as the sum of protons and neutrons in the nucleus of the atom. The difference in the mass (mass number) of isotopes is a result of the varying number of neutrons in the nucleus of their atoms. As a result, the same element can have a different mass and density. Isotopy is a phenomenon whereby atoms of the same element have the same atomic number but different mass number. The discovery of isotopes has shown that not all atoms of the same elements are similar in every aspect. Atoms of the same element are identical to each other in every aspect because they have the same shape and mass, while atoms of different elements are different in all respect.Please read on elements and characteristics of elements here. Quarks: A quark is a fast moving energy and is comprised of both the protons and neutrons in the nucleus of an atom. Neutrons: These particles have no charge (neutral) and are found in the nucleus of an atom.Įlectrons: They are negatively charged particles that revolve round the shell of atoms. Protons: They are positively charged particles in the nucleus of an atom.
