Lesson Plan Day: 45         10/25

Teacher: P. Kirk

Subject: Science

Course: Chemistry


Structure of the nucleus and the "loss" of mass caused as nuclear matter is converted to binding energy.

Stable and unstable ratios of protons and neutrons. 

How nuclear reactions affect the nucleus of an atom. 

Radioactive decay leads to more stable isotopes. During decay particles and energy are released.  

Half-life is the time needed for one half of an amount of radioactive material to decay.

Radioactive nuclides become stable through a series of decays.

Nuclides can become radioactive naturally or artificially.  


HS.PS1.C: Nuclear Processes
Nuclear processes, including fusion, fission, and radioactive decays of unstable nuclei, involve release or absorption of energy. The total number of neutrons plus protons does not change in any nuclear process.

Section 21.1: Nuclear reactions affect the nucleus of an atom.


Complete nuclear reactions by determining particles produced.  


nucleon, nuclide, mass defect, binding energy, shell model, magic number, nuclear reaction, transmutation  

radioactive decay, nuclear radiation, radioactive nuclide, alpha particle, beta particle, positron, electron capture, gamma ray, half-life, decay series, parent nuclide, daughter nuclide, artificial transmutation, transuranium element.  


S will demonstrate their understanding of nuclear decay and the particles and/or energy produced in a nuclear reaction. 


T will copy quizzes and blank periodic tables. Monitor S progress and minimize the chance for student cheating during the quiz. 


Students will need a periodic table and a calculator.  


The Decay Half-life Quiz is a summative assessment which will require students to complete nuclear equations, predict particles formed as a result of a nuclear reaction.
