The class outcomes, expectations, and grading are explained. A history of radioelement discovery and radiation research is presented. The Chart of the Nuclides and Table of the Isotopes are discussed and used. Atomic properties, nuclear nomenclature, X-rays, types of decays and physical forces are introduced.
Finished listening to the lecture and submitted the quiz. Still need to finish reading the first chapter from the book and do some practice questions. Brains a bit rusty but this class should dust the cobwebs off.
ReplyDeletethanks for the comments. I am sure you will do great!
DeleteFinished the lecture, reading the cart of nuclides overview section helps afterward
ReplyDeletethanks for the comments, I hope you enjoyed the reading.
DeleteFinished the lecture videos. I will say that things do go really fast around explaining the fission products.
ReplyDeletethanks for the comment Brian. We will have more detailed lectures on all the subject matter covered in the introduction.
DeleteThis is considerably dense material. I don't know if I'm understanding exactly what I'm supposed to be reading. I just feel like I've read a bunch of material and have yet to come across most of the information pertaining to the PDF quiz. And I just answered my own question by looking at the Table of Nuclides which I am now assuming wasn't meant for us to read the whole book but just look at and understand the charts. I think I might go take a moment and cry from reading all of that. Well, I've finished the PDF quiz so....yeah.
ReplyDeleteThe front part of the chart of the nuclides is part of the reading. The information on how to use the chart of the nuclides is the main feature of this lecture. Your PDF quiz 1 is all correct, so I trust you gained some comprehension of the subject matter. Great job!
DeleteThere is a lot of information in this lecture, however I'm going to assume we cover most of it in more detail in the coming lectures, hence why this lecture was called 'introduction'. I did have a few questions. With x-rays, and the removal of k shell electrons, why is it the k shell? I may have a hole in my education, but I don't recall the shells ever being named-are they?
ReplyDeleteAlso with spin and parity, could you provide brief definitions as a refresher?
I haven't finished the quiz and problems, and I'm working on the reading. Hopefully things will start to fit into the puzzle correctly for me!
Correct on the introduction. The material will be covered in more detail in other lectures.
DeleteFinished the lecture videos and submitted the quiz. Looking at the charts in the book while listening to the lecture helped clarify the information covered.
ReplyDeleteThanks, great to hear.
DeleteMaybe I am a bit slow, but how do I submit the quizzes? Is it just the submit button in the right upper corner? How do I know if the submission was successful? And do we have to log into the class webpage? Other than that I am enjoying the videos and power point format of the course.
ReplyDeleteYou can submit via the submit button. The quiz can also be attached to an e-mail. Please review the lecture at http://radchem.nevada.edu/classes/chem312/lect%200%20online%20lect.html
DeleteThere is no login for the course.
E-mails have been sent to those who have yet to submit PDF quiz 1.
ReplyDeleteI have now submitted the quiz for this lecture. There is a lot of material here for me to digest so it took me a while to get everything sorted out mentally. The part of the lecture relating to the chart of the nuclides helped me understand it better.
ReplyDeleteThanks for the comments. I would much rather that you comprehend the material. If you look at the top of the quiz you will see that it is not due until 26 January.
DeleteI just watched the lectures and submitted the quiz. I really appreciate that the lectures are around a half hour each but the information is understandable. Going over the chart of the nuclides was incredibly helpful. These lectures got me excited for all of the interesting reactions and applications of radiochemistry we will see this semester.
ReplyDeleteFinally done with the lecture and quiz. Had fun exploring the chart of the nuclides and discovering the great amount of information contained in it. I also started to make my way through the Khan Academy section on nuclear chemistry which offers a great starting point to the basics of NC. While browsing, I found this cool, retro video on you-tube that uses great, and somewhat creepy, images to explains in some detail the chemistry and making of an atomic bomb.

Sorry about the delay but I will submit the Quiz tonight. I'm having some trouble with the Q-value calculator, but the power points were informative. I'm looking forward to more practice in reading the Chart of the Nuclides since it provides so many details.
ReplyDeleteI just realized I submitted the wrong Quiz. My apologies to professor Czerwinski. If you are willing to grade it, I will send in Quiz 1 instead of PDF Quiz 2 later today.
ReplyDeleteLate comment post for Lecture 1, but I had a chance to print out and read Chapter 1 of Modern Nuclear Chemistry over the weekend. Both the lecture and text helped me relearn and review fundamental radiochemistry topics.
