Quiz 7.1

Radioactivity– 7.2 describe the structure of an atom in terms of protons, neutrons and electrons and use symbols such as 14C6 to describe particular nuclei

Radioactivity–7.3 know the terms atomic (proton) number, mass (nucleon) number and isotope

Radioactivity–7.4 know that alpha (α) particles, beta (β−) particles, and gamma (γ) rays are ionising radiations emitted from unstable nuclei in a random process

Radioactivity–7.5 describe the nature of alpha (α) particles, beta (β−) particles, and gamma (γ) rays, and recall that they may be distinguished in terms of penetrating power and ability to ionise

Radioactivity–7.6 practical: investigate the penetration powers of different types of radiation using either radioactive sources or simulations

7.7 describe the effects on the atomic and mass numbers of a nucleus of the emission of each of the four main types of radiation (alpha, beta, gamma and neutron radiation)

Radioactivity–7.8 understand how to balance nuclear equations in terms of mass and charge

Radioactivity–7.9 know that photographic film or a Geiger−Müller detector can detect ionising radiations

Radioactivity–7.10 explain the sources of background (ionising) radiation from Earth and space

Radioactivity–7.11 know that the activity of a radioactive source decreases over a period of time and is measured in becquerels

Radioactivity–7.12 know the definition of the term half-life and understand that it is different for different radioactive isotopes

Radioactivity–7.13 use the concept of the half-life to carry out simple calculations on activity, including graphical methods

Radioactivity–7.14 describe uses of radioactivity in industry and medicine

Radioactivity–7.15 describe the difference between contamination and irradiation

Radioactivity–7.16 describe the dangers of ionising radiations

Fission and fusion– 7.17 know that nuclear reactions, including fission, fusion and radioactive decay, can be a source of energy

Fission and fusion–7.18 understand how a nucleus of U-235 can be split (the process of fission) by collision with a neutron, and that this process releases energy as kinetic energy of the fission products

Fission and fusion–7.19 know that the fission of U-235 produces two radioactive daughter nuclei and a small number of neutrons

Fission and fusion–7.20 describe how a chain reaction can be set up if the neutrons produced by one fission strike other U-235 nuclei

Fission and fusion–7.21 describe the role played by the control rods and moderator in the fission process

Fission and fusion–7.22 understand the role of shielding around a nuclear reactor

Fission and fusion–7.23 explain the difference between nuclear fusion and nuclear fission

Fission and fusion–7.24 describe nuclear fusion as the creation of larger nuclei resulting in a loss of mass from smaller nuclei, accompanied by a release of energy

Fission and fusion–7.25 know that fusion is the energy source for stars

Fission and fusion–7.26 explain why nuclear fusion does not happen at low temperatures and pressures, due to electrostatic repulsion of protons
