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. Part one viewing time 38 minutes, part 2 viewing time 42 minutes. The PDF quiz 1 is assigned 17-Jan-17 and due 24-Jan-17.
I just completed the lecture and submitted the quiz via email. I'm a little confused about the thermal neutron absorption cross section data, is this something we will cover later in the course?
ReplyDeleteThe other information will be covered in the course. For now the goal is to be able to identify data. The thermal neutron cross section will be covered in Lecture 2, then in more detail in the course.
Deletethanks for the question!
i have no ideal for question 3, can you give me a sample?
ReplyDeletean updated pdf quiz is now available
DeleteI have updated PDF quiz 1. Question 3 now has pulldown answers. Please use this PDF quiz, the webpage will be updated. The website http://physics.nist.gov/PhysRefData/XrayTrans/Html/search.html can also be used. One can also use the Z and energy data to generate an equation to solve. From the graph in question 3 figure the relationship of Z versus square root E should be linear.
ReplyDeleteI just submitted the quiz via email. i just solve the question 3 by put the element in the chart and get the answer from the website that you provide, is it right?
ReplyDeleteyour answers are correct for question 3
DeleteI've completed the lecture as well as the associated quiz. Major difficulties when attempting to submit.
ReplyDeletePDF quiz 1 is attached to the email you sent. thanks for the submission.
DeleteI have submitted the quiz via email
ReplyDeletethanks for the comments on lecture 1
DeleteLecture parts 1 and 2 are completed, moving onto lecture 2
ReplyDeletethanks for the PDF quiz and comments
DeleteDr. Czerwinski I have sent you my pdfquiz1 via e-mail. I thought the discovery of radioactivity was interesting. also,not sure if other students had issues with some of the weblinks such as the course reading list?? I just get an error or a blank site.
ReplyDeletethanks for the comments. Please let me know which readings are errors.
Delete*curium discovery
Delete*table of isoptopes

I tried to again today and still no luck.
thanks for the comments. I do not have a problem with the nuclear and radiochemistry. Try

I have completed Lecture 1 and the corresponding PDF quiz. There was a lot to learn in this lecture! Very neat.
ReplyDeletethanks for the comments!
DeleteI completed both parts of the lecture as well and sent in PDF quiz 1. A ton of interesting information, I enjoyed.
ReplyDeletethanks for the comments!
DeleteI forgot to mention that I emailed you the quiz as a PDF attachment. I hope it made it to you okay!
ReplyDeletethanks for your contribution
DeleteLectures part 1 and part 2 are completed. I've submitted quiz 1 via email attachment yesterday (Sunday).
ReplyDeletethanks! I appreciate the pdf quiz and comments
DeleteI completed the lectures and I have submitted quiz 1.
ReplyDeleteI appreciate your comments and pdf quiz!
DeleteHi! I sent PDF Quiz 1 to you as an attachment through my email after I went over both parts of lecture 1. Hope you received it.
ReplyDeletePDF quiz received!
DeleteI finsihed the lecture and submitted the PDF quiz, I sloved number three with the equation of the line, but I am not sure how to get the number without the line. I don't think I really understand that question
ReplyDeleteFrom the figure we see the relationship between Z and the square root of the frequency. The relationship between E and v is E=hv. Since this is true, then the relationship between Z and E is bases on square root of E. Using the data in the question one can generate the equation square root E = 3.329Z-6.18. Input Z and you get E. What I was really looking for as the general trend as Z increase E increase. Based on the data there were boundaries for the values. For example U has a Z of 92. This must be above value for Hg, Z= 80. The only possible answer is 94650 eV. Tm and Lu are at Z= 69 and 71. The values must be near Yb, with Tm lower.
DeleteThank you,
DeleteThat makes sense and is also what I did to solve the question, I just thought maybe I was missing something. I resubmitted the PDF quiz
thanks for PDF quiz 1
ReplyDeleteI submitted my pdf quiz 1 and resubmitted quiz 0

ReplyDeleteI just completed lecture 1 and submitted quiz 1. Finally a class I can listen while at work.
ReplyDeleteThanks for the comment. I am happy to provide the entertainment! I do think the flexibility can be usefulu.
DeleteHi, I just submitted my quiz. Sorry it's a bit late.
ReplyDeleteNot late at all. All assignments for CHEM 312 are due to 11:59 PM on the due date.
Deletequiz 1 complete, though #3 was confusing
ReplyDeleteSubmitted quiz #1.
ReplyDeleteQuiz 1 is completed. I'm not sure if I'm behind but it took me a while to find out what the Cavendish laboratory was and not to mention I still don't completely understand question 3 as I couldn't connect Z with E. Perhaps I should be reading the additional literature provided. I mean that is a given, but perhaps I missed something in the mp4 videos. I found this lecture interesting, particularly the section on history.
ReplyDeleteLecture 1 quiz submitted. Thanks!
ReplyDeleteQuiz sent. Many issues with filling out after downloading the PDF.
