The correct Answer is:
To determine the number of subatomic particles that are the same in a chlorine atom and a chloride ion, we will analyze the components of both species. ### Step 1: Understand the Composition of Chlorine Atom A neutral chlorine atom (Cl) has: - **Protons**: Chlorine has an atomic number of 17, which means it has 17 protons. - **Electrons**: In a neutral atom, the number of electrons equals the number of protons, so it also has 17 electrons. - **Neutrons**: The most common isotope of chlorine is chlorine-35, which has 18 neutrons (35 - 17 = 18). ### Step 2: Understand the Composition of Chloride Ion A chloride ion (Cl⁻) is formed when a chlorine atom gains one electron: - **Protons**: The number of protons remains the same at 17. - **Electrons**: The chloride ion has 18 electrons (17 from the neutral atom + 1 gained electron). - **Neutrons**: The number of neutrons remains the same at 18. ### Step 3: Compare the Subatomic Particles Now, we compare the subatomic particles: - **Protons**: Both the chlorine atom and the chloride ion have 17 protons. - **Electrons**: The chlorine atom has 17 electrons, while the chloride ion has 18 electrons. - **Neutrons**: Both have 18 neutrons. ### Conclusion The number of protons is the same in both the chlorine atom and the chloride ion. Therefore, the answer to the question is that the number of protons is the same. ### Final Answer The number of protons is the same in the chlorine atom and the chloride ion. ---
