**Text Transcription:** Refer to the figure below. (Hint: This isotope is a neutral atom.) What isotope is represented? Provide both the element name and mass. Describe how you determined this. **Diagram Explanation:** The diagram represents a model of a simple atom. It has: 1. **Nucleus:** - Contains 2 red spheres and 1 purple sphere. These likely represent protons and neutrons, respectively. This suggests the nucleus contains 3 nucleons (a combination of protons and neutrons). 2. **Electron Shell:** - There are 2 blue spheres orbiting the nucleus, which represent electrons. **Analysis:** - **Number of Protons:** The number of red spheres (2) indicates there are 2 protons. The element with atomic number 2 is Helium. - **Mass Number:** The total number of nucleons is 3 (2 protons + 1 neutron), indicating the mass number is 3. - **Element and Isotope:** Based on the number of protons, this is a Helium atom. With the mass number of 3, the isotope is Helium-3. Therefore, the diagram represents the Helium-3 isotope.
