iGCSE Physics - 5.2.3 Radioactive Decay SUPPLEMENT

**This Powerpoint specifically uses the Cambridge iGCSE Syllabus and covers all criteria for – Unit 5.2.3 Radioactive Decay SUPPLEMENT
**

Know that isotopes of an element may be radioactive due to an excess of neutrons in the nucleus and/or the nucleus being too heavy

Describe the effect of α-decay, β-decay and γ-emissions on the nucleus, including an increase in stability and a reduction in the number of excess neutrons; the following change in the nucleus occurs during β-emission
neutron → proton + electron

Use decay equations, using nuclide notation, to show the emission of α-particles, β-particles and γ-radiation

**Every Powerpoint includes learning objectives, a starter and plenary, suitable activities and review questions with mark scheme. We also provide a free pdf version of the file so it can easily be printed for students as a handout or uploaded to the school VLE system
