In a neutral atom, the number of protons equals the number of electrons. Given that tin has an atomic number of 50, this means it has:
- **Protons:** 50
- **Electrons:** 50 (since the atom is neutral)
- **Neutrons:** To find the number of neutrons, subtract the atomic number from the mass number.
The mass number of tin is given as 119, so:
**Neutrons = Mass Number - Atomic Number = 119 - 50 = 69**
Therefore, in a neutral atom of tin, there are:
- **50 protons**
- **50 electrons**
- **69 neutrons**
The correct answer is: **50 protons, 50 electrons, 69 neutrons.**
- **Protons:** 50
- **Electrons:** 50 (since the atom is neutral)
- **Neutrons:** To find the number of neutrons, subtract the atomic number from the mass number.
The mass number of tin is given as 119, so:
**Neutrons = Mass Number - Atomic Number = 119 - 50 = 69**
Therefore, in a neutral atom of tin, there are:
- **50 protons**
- **50 electrons**
- **69 neutrons**
The correct answer is: **50 protons, 50 electrons, 69 neutrons.**
