# 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 $^{12}\text{C}$?**
