Lesson Plan: Positron Emission
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to solve nuclear equations involving positron emission.
Objectives
Students will be able to
- recall that is the antiparticle of ,
- recall that is just another name for a positron,
- recall that when a nucleus undergoes decay, it emits a positron and an electron neutrino,
- recall that when a nucleus undergoes decay, its relative charge decreases by 1, its atomic number decreases by 1, and its mass number stays the same,
- solve nuclear equations involving decay,
- interpret nuclear decay charts that show decay,
- interpret nuclear ball diagrams that show decay.
Prerequisites
Students should already be familiar with
- what electrons and positrons are,
- what electron neutrinos and electron antineutrinos are,
- the basic structure of atoms.
Exclusions
Students will not cover
- electron capture,
- alpha decay,
- gamma decay,
- neutron emission,
- proton emission.
