How is the radioactivity of an element affected when it undergoes a chemical change to form a chemical compound ? Give reason for your answer.

Explanation

**Step-by-Step Solution:**

1. **Understanding Radioactivity**:
- Radioactivity is a process by which unstable atomic nuclei lose energy by emitting radiation. This process is a nuclear phenomenon, meaning it originates from the nucleus of the atom.

2. **Chemical Changes vs. Nuclear Changes**:
- Chemical changes involve the rearrangement of electrons in the outer shells of atoms, leading to the formation of chemical compounds. These changes do not affect the nucleus of the atom.
