DWU #3- What is the average atomic mass of element "X" if it has the following isotopes and percent relative abundance? X-131, 8.2500%; X-128, 90.000% and X-133, 1.7500%
I checked homework and we quickly went over it. I also collected the element cubes and the Metal Vs. Non-Metal Lab.
We discussed types of radiation and radioactive decay. Also, we collected the data for the Half-Life Demo lab, but didn't have time to discuss them.
