- UK-GCSE-SCIENCE-PHYS-AST-01General Certificate of Secondary Education (GCSE) · Science · Year 11 (GCSE) · Grade 10Nuclear atom and isotopes
- UK-GCSE-SCIENCE-PHYS-AST-01-04General Certificate of Secondary Education (GCSE) · Science · Year 11 (GCSE) · Grade 10recall that atomic nuclei are composed of both protons and neutrons, that the nucleus of each element has a characteristic positive charge, but that atoms of the same elements can differ in nuclear mass by having different numbers of neutrons
- UK-GCSE-SCIENCE-PHYS-AST-01-05General Certificate of Secondary Education (GCSE) · Science · Year 11 (GCSE) · Grade 10relate differences between isotopes to differences in conventional representations of their identities, charges and masses
- UK-GCSE-SCIENCE-PHYS-AST-02General Certificate of Secondary Education (GCSE) · Science · Year 11 (GCSE) · Grade 10Absorption and emission of ionizing radiations and of electrons and nuclear particles
- UK-GCSE-SCIENCE-PHYS-AST-02-01General Certificate of Secondary Education (GCSE) · Science · Year 11 (GCSE) · Grade 10recall that 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
