It seems there is a small confusion in the question regarding Thallium's atomic mass and atomic number. The correct atomic number for Thallium (Tl) is 81, and its atomic mass is approximately 204.38 amu (atomic mass units).
However, based on the atomic number of 15, that describes Phosphorus (P), not Thallium.
### For Phosphorus (P, Z = 15):
1. **Number of Protons:**
The atomic number (Z) is 15, which is also the number of protons.
**Protons = 15**
2. **Number of Electrons:**
In a neutral atom, the number of electrons equals the number of protons.
**Electrons = 15**
3. **Number of Neutrons:**
To find the number of neutrons, subtract the number of protons from the atomic mass (rounded to the nearest whole number). The commonly accepted atomic mass for phosphorus is about 31.
\[
\text{Neutrons} = \text{Atomic Mass} - \text{Protons} = 31 - 15 = 16
\]
**Neutrons = 16**
**Summary:**
- Protons: 15
- Neutrons: 16
- Electrons: 15
### Electron Configuration:
The electron configuration for phosphorus (P) is based on the distribution of electrons in atomic orbitals:
\[
\text{Electron Configuration: } 1s^2 \, 2s^2 \, 2p^6 \, 3s^2 \, 3p^3
\]
### Atomic Structure:
To visualize the atomic structure, consider the following:
- The first energy level (n=1) can hold up to 2 electrons, which would fill the 1s orbital.
- The second energy level (n=2) can hold up to 8 electrons, filling 2s and 2p orbitals.
- The third energy level (n=3) can hold up to 18 electrons; in phosphorus, it has 5 electrons in the 3s and 3p orbitals (2 in 3s and 3 in 3p).
Here's a simplified representation of the atomic structure:
```

The total electrons are shown in their respective orbitals, illustrating how they fill up.
### Conclusion
You provided details for Thallium but mentioned atomic number 15, which is actually Phosphorus. The elemental properties have been clarified for Phosphorus, with details on protons, neutrons, electrons, electron configuration, and a basic representation of its atomic structure. If you need information specifically about Thallium, please let me know!
