Topic Outline--print off before 1/4/11

bulletUnit Objectives This is a summary of the syllabus statements that are detailed on the topic outline.
bulletUnderstand the nuclear model of the atom and atomic energy levels
bulletExplain the structure of an atom and interactions within the nucleus
bulletUnderstand and explain the general process of natural radioactive decay
bulletDescribe the properties and characteristics of alpha particles, beta particles, and gamma rays
bulletUnderstand and describe the processes and products of alpha decay, beta decay, and gamma decay
bulletDescribe the biological effects of exposure to ionizing radiation
bulletExplain nuclear stability
bulletDescribe radioactive half-life; use a decay curve to determine the half-life of a nucleus; solve problems involving half-lives
bulletUnderstand and describe the processes of fission and fusion
bulletUnderstand and apply Einstein's mass-energy equivalence to determine energy produced during nuclear reactions
bulletUnderstand the concept of binding energy, including the interpretation of a binding energy curve

bulletUnit Equations--

E = mc2

The next equations are not in your data booklet, but will also be handy to know (these you must memorize through repeated practice...you will NOT be given these for any test or quiz!):

mdefect = mexpected - mmeasured

n = (½)x·N       
where
n is the number of particles (or the mass) remaining after x half-lives and N is the initial quantity

 

 

bulletUnit Notes
bulletIntro to Nuclear Physics--a history--last year's version...will be updated when I remember to bring my usb drive home :)  however, there are virtually no differences (except a typo or two) between this and what we're using this year.
