the topic of nuclear chemistry. Our focus will be to what
radiation is and how and why various atoms undergo radioactive decay.
We will also discuss the rates of decay, often expressed in
of a half-life. Finally, we will discuss binding energy and
relate the results of binding energy calculations to fission and
the course of the unit, there will be ~2 WebAssign Reading Sheets (optional), one
WebAssign problem set and 2-3
labs. We will be following
Chapter 19 of the textbook (with a short dabbling into section 2 of
Chapter 2). You should read it carefully and use
it as a frequent
reference. A unit packet will be distributed on the first day
the unit; it will be used throughout the unit as we learn new
skills and incrementally progress towards understanding the
and mathematics of related
to nuclear chemistry.
Much of our coverage will be conceptual in nature. Due to
time, the unit will be cut short in order to allow time for a very
brief preview to the final exam.
Regarding the Nuclear Chemistry WebAssigns
There are three Nuclear Chemistry
WebAssigns that are entirely optional. They will be the basis of the
questions asked on all daily quizzes as well as on the short quest at
the end of the unit (Monday, 6/6). The value of the WebAssigns will be
related to learning points
from this unit (as opposed to earning points
). All WebAssigns are due on Sunday, June 5 at 6 pm. After this time, the keys may be viewed.

In Its Element
Much of what
this year will in one way or another be related to the chemical
elements and their organization into a periodic table. The Royal
Society of Chemistry (in London) has put together a collection of
intriguing weekly podcasts that focus on the various elements of the
periodic table. The collection of broadcasts are titled Chemistry in It's Element
available online or through ITunes. It's worth a look (and a listen) at
some time during the year. Visit their periodic table and click the
headphones to listen to a podcast on the element of your choice. Visit Chemistry in Its Element
