Question
![**Understanding Atomic Structure: Protons, Neutrons, and Electrons**
Given the nuclear symbol for an isotope:
\[ \, _{38}^{80} \text{Sr} \]
**Task:**
Determine the number of protons, neutrons, and electrons in a neutral atom of this isotope.
**Explanation of the Symbol:**
- **Protons:** The atomic number is the subscript (bottom number), which represents the number of protons. In this case, the atomic number is 38. Therefore, the isotope has 38 protons.
- **Neutrons:** To find the number of neutrons, subtract the atomic number from the mass number (superscript or top number). The mass number is 80. Thus, the number of neutrons is \( 80 - 38 = 42 \).
- **Electrons:** In a neutral atom, the number of electrons is equal to the number of protons. Therefore, there are 38 electrons.
**Summary:**
- Protons: 38
- Neutrons: 42
- Electrons: 38
**Interactivity:**
- Users are prompted to enter their answers in the provided fields for protons, neutrons, and electrons.
- The "Submit Answer" button allows users to check their responses.
- If the group is not satisfied with their attempts, they can use the "Retry Entire Group" option.
- Note that there are 7 more group attempts remaining.
