20.1 Introduction to Nuclear Chemistry | General Chemistry
Chad provides an introduction to Nuclear Chemistry, the chapter where we finally get past the electrons and talk about the nucleus. The symbols for all the common nuclear particles are presented (alpha particle, neutron, proton, beta particle, positron, gamma ray), and students are reminded how to determine the number of protons and neutrons from the atomic number and mass number. The trend in penetrating power is also provided and explained.
Four guidelines for trends in radioactivity and then presented and explained:
1. Elements with atomic number greater than 83 are radioactive.
2. Nuclei having even numbers of protons and/or neutrons are more stable (less likely to be radioactive).
3. Nuclei having the proper N/Z (neutron to proton) ratio are less likely to be radioactive -- 1 for lighter elements and a little greater than 1 for heavier elements.
4. Nuclei having magic numbers (2,8,20,28,50,82,126) of protons and/or neutrons tend to be less likely to be radioactive.
I've embedded this playlist as a course on my website with all the lessons organized by chapter in a collapsible menu and much of the content from the study guide included on the page. Check this lesson out at www.chadsprep.com/chads-gener...

Hey Chad, I used to watch you in college and for the mcat. I am about to finish residency in emergency medicine. Your name just popped into my head, good to see you around making content. I still remember a lot from your original videos. Best to you

Thanks Matt and congratulations! Just about to finish your residency...you have been on this road a while. It has to feel good. Wish you the best also!
Ive been interested in nuclear chemistry for a couple years. I’m so glad i stumbled on your channel! Learning so much in a very easy to understand way! Thank you!

What's the most efficient way to generate muons? I mean like if I want to make my own in an accelerator, not just waiting for cosmic rays happening to be going in the right direction... Can It be done with very high energy electrons or does it have to be protons, what's a good target etc..?
Hey Chad, I was curious if you have any gen chem videos over chemical kinetics. If so, I can't seem to find them. Thank you in advance

Wouldn't the penetrating power of a neutron exceed that of a proton due to its lack of electromagnetic interactions?
nice sir

i thought neutrons were highly penetrating, being more penetrating than alpha and beta as well.

Neutrons are highly penetrating. Did you find a part of the video that contradicts this?
