17 objective pages available
Composition and Charge of Atomic Nuclei1 objectives
- Retrieve and apply knowledge of atomic nuclei are composed of both protons and neutrons, that the nucleus of each element has a characteristic positive charge.
Understanding Isotopes: Atoms with Different Nuclear Masses1 objectives
- Retrieve and apply knowledge of atoms of the same elements can differ in nuclear mass by having different numbers of neutrons.
Understanding Nuclear Notation and Isotopes1 objectives
- Apply the conventional representation for nuclei to relate the differences between isotopes.
Unstable Nuclei and Radioactive Decay1 objectives
- Retrieve and apply knowledge of some nuclei are unstable and may emit alpha particles, beta particles, or neutrons, and electromagnetic radiation as gamma rays.
Understanding Radioactive Decay and Nuclear Changes1 objectives
- Develop knowledge and skill in the emission of alpha particles, beta particles, gamma radiation and neutrons to possible changes in the mass or the charge of the nucleus, or both.
Understanding Radioactive Decay Equations1 objectives
- Apply names and symbols of common nuclei and particles to write balanced equations that represent radioactive decay.
Understanding Radioactive Decay Equations1 objectives
- Develop knowledge and skill in equations representing the emission of alpha, beta or gamma radiation in terms of the masses, and charges of the atoms involved.
Atomic Structure, Electrons, and Ionisation1 objectives
- Retrieve and apply knowledge of in each atom its electrons are arranged at different distances from the nucleus, that such arrangements may change with absorption or emission of electromagnetic radiation and that atoms can become ions by loss of outer electrons.
Radiation Generation and Absorption by Atoms and Nuclei1 objectives
- Retrieve and apply knowledge of changes in atoms and nuclei can also generate and absorb radiations over a wide frequency range.
Half-Life and Random Radioactive Decay1 objectives
- Account for the concept of half-life and how this is related to the random nature of radioactive decay.
Understanding Radioactive Decay and Half-Life (Higher)1 objectives
- Work out the net decline, expressed as a ratio, during radioactive emission after a given (integral) number of half-lives.
Understanding Penetration Properties of Radioactive Emissions1 objectives
- Retrieve and apply knowledge of the differences in the penetration properties of alpha particles, beta particles and gamma rays.
Understanding Contamination and Irradiation from Radioactive Sources1 objectives
- Retrieve and apply knowledge of the differences between contamination and irradiation effects and compare the hazards associated with these two.
Radioactive Hazards and Half-Life1 objectives
- Account for why the hazards associated with radioactive material differ according to the half-life involved.
Uses of Nuclear Radiation in Medicine1 objectives
- Communicate the key features of the different uses of nuclear radiations for exploration of internal organs, and for control or destruction of unwanted tissue.
Unstable Nuclei, Radiation, and Chain Reactions1 objectives
- Retrieve and apply knowledge of some nuclei are unstable and may split, and relate such effects to radiation which might emerge, to transfer of energy to other particles and to the possibility of chain reactions.
Understanding Nuclear Fusion1 objectives
- Communicate the key features of the process of nuclear fusion.
