An atom of oxygen contains protons, neutrons and electrons. Indicate where each particle is found in the atom by specifying whether they are "in the nucleus" or "orbiting the nucleus":
An atom of oxygen contains 8 protons, 10 neutrons and 8 electrons.
(i) State the proton number of this oxygen.
An atom of oxygen contains 8 protons, 10 neutrons and 8 electrons.
(ii) State the nucleon number of this oxygen.
Oxygen has many different isotopes.
(i) Explain the meaning of the term isotope.
Oxygen has many different isotopes.
(ii) The nuclide notation for the oxygen in (b) is 0818O^{18}_{\phantom{0}8}\text{O}0818O. Suggest the nuclide notation for another possible isotope of oxygen.
284 exam-style questions on CIE IGCSE Physics 5.1 The nuclear model of the atom, covering 5.1.1a Structure of the atom and ions, 5.1.1b Alpha-particle scattering, 5.1.2a Composition of the nucleus and isotopes, 5.1.2b Proton number, nucleon number and nuclide notation, and 5.1.2c Nuclear fission and nuclear fusion. Each one has a worked solution and a mark scheme showing where the marks go.
