Question

How many protons, neutrons, and electrons does carbon-13 have?
Responses

6 protons, 6 electrons, 6 neutrons
6 protons, 6 electrons, 6 neutrons

7 protons, 7 electrons, 6 neutrons
7 protons, 7 electrons, 6 neutrons

6 protons, 6 electrons, 7 neutrons
6 protons, 6 electrons, 7 neutrons

7 protons, 7 electrons, 7 neutrons

Answer 1

Carbon-13 is an isotope of carbon. It has the following characteristics:

- Protons: Carbon has an atomic number of 6, which means it has 6 protons.
- Electrons: In a neutral atom, the number of electrons is equal to the number of protons, so carbon-13 also has 6 electrons.
- Neutrons: The mass number of carbon-13 is 13. The number of neutrons can be calculated using the formula:
\[ \text{Neutrons} = \text{Mass number} - \text{Protons} \]
So, for carbon-13:
\[ \text{Neutrons} = 13 - 6 = 7 \]

Therefore, carbon-13 has:
- 6 protons
- 6 electrons
- 7 neutrons

The correct response is: **6 protons, 6 electrons, 7 neutrons.**
