Question

### Nuclear Reactions Worksheet

**Exercise 7: Writing Balanced Nuclear Equations**

Write a balanced nuclear equation for the following reactions and identify x, x, and y.

a) \( X (It-2, H-1) Se-81 \)

b) \( Fe-56 (H-2, He-4) X \)

c) \( Pd-106 (x, y) Ag-109 \)

---

**Instructions for Students:**

1. **Identify x, x, and y:** Determine the unknown particles or elements labeled as x in each equation.
2. **Balance the Equation:** Ensure that the sum of the atomic numbers (protons) and mass numbers (nucleons) are equal on both sides of the reaction.

**Example Explained:**

For a reaction labeled as \( X (It-2, H-1) Se-81 \):
- \( X \) represents an unknown reactant.
- \( It-2 \) indicates interaction or change involving two atoms of a particular isotope, while \( H-1 \) suggests the involvement of a hydrogen isotope.
- \( Se-81 \) represents an isotope of Selenium with a mass number of 81.

**Steps:**

1. Use the periodic table to identify the elements based on their atomic numbers and symbols.
2. Balance the mass numbers and atomic numbers for the reactants and products.

**FAQs on Nuclear Reactions:**

- **What are isotopes?**
Isotopes are variants of a particular chemical element that share the same number of protons but have different numbers of neutrons.

- **How do nuclear reactions differ from chemical reactions?**
In nuclear reactions, the nuclei of atoms are altered, resulting in the change of one element into another. In contrast, chemical reactions involve the rearrangement of electrons around atoms but the nuclei remain unchanged.

By practicing these steps, students can enhance their understanding of nuclear reactions and isotopic notations.
