Complete the problems below being sure to show your work. If you need to lookup nuclear data from an external source please reference the source in your solutions.
Problems
1. How many neutrons and protons are there in the nuclei of the following atoms:
| Atom | Protons | Neutrons |
|---|---|---|
^7\text{Li} |
3 | 4 |
^{24} \text{Mg} |
12 | 12 |
^{135}\text{Xe} |
54 | 81 |
^{209}\text{Bi} |
83 | 126 |
^{222}\text{Rn} |
86 | 136 |
**2. The atomic weight of ^{59}\text{Co} is 58.93319. How many times heavier is ^{12}\text{C}? ** |
||
\frac{ ^{59}\text{Co}}{^{12}\text{C}} = \frac{58.93319}{12.00000} = 4.91110 \text{ times larger} |
3. How many atoms are there in 10g of ^{12}\text{C}?
