Lesson 16

Today we learned that a nuclear fission can result in a chain reaction that produces a lot of energy! You may be wondering what a chain reaction is, I'll tell ya! A chain reaction is when a neutron emits striking the nuclei causing them to split a part. Then we learned that when radioactive decay, fusion, fission and a nuclear process occurs a new element is formed! Radioactive decay is when an atom emits radiation or a particle from the nucleus and the atom becomes more stable! :) I have already previously explained fusion and fission, so look at my other blog posts if you dont know what they are! we also learned that the mass changes when protons and neutrons are added or lost ( should be review! ). Then we had more practice with alpha, beta and fusion equations. As stated in my other blogs, alpha is when the amu decreases by 4, and the atomic number decreases by 2. Beta is when the atomic number increases by one. And fusion when 2 nuclei join to make a larger nucleus. I would show you an example but it's hard on the iPad! However, I did a few in my homework if you need to see one!
