Question 44 2 points Save Answer Samarium-153 (Sm-153) EDTMP is the common name for a compound used to treat bone cancer. Your lab receives a sample containing 16.0 wg of Sm-153 and after 6 days you have 2.0 wg of the sample left. This means that the half-life of Sm-153 is 2 days.

2 Consider a toy model of an atomic nucleus. In this picture, a proton is considered to move through a uniform sphere of charge (p 1)e, where p is the number of protons in the nucleus and e is the charge on the proton. The radius of the nucleus is given by the formula In the above A is the atomic mass number (protons plus neutrons) and ro 1.3 × 10-15 m. For this model, find the force on a...
