-The process looks nearly identical every time that the simulation is run. This shows that Radiation is more of a statistical probability distribution for a group of like atoms. xiv) 1) What ideas do you have, to explain the similarities and differences in the data and also your predictions? -The trend remains consistent, in that it is exponential decay. The minute differences in the data points can be attributed to the nature of radiation as a probability distribution. It is likely that ½ of the mass will radioactively decay after it’s half life has passed, and then ¼, ⅛, and so on. 2) Is it reasonable to assume that if you start with 10 atoms of Polonium, that 0.5s later only 5 will remain? What if you start with 500 atoms? -Yes it is, assuming that the t 1/2 for Po is 0.5s. With 500 atoms, at t 1/2 , there will be 250 atoms. Beta Radiation MAIN QUESTION 2: Why does hydrogen become helium after beta decay? A neutron ejects an antineutrino and an electron (beta radiation) and the neutron is then

Khan Academy. Accessed January 24, 2017. . 2) Explain why the mass number remains unchanged after decay -The mass number remains unchanged because the proton is converted to a neutron, which does not change the amu of the atom. xi)

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
