The fixed path along which an electron revolves around the nucleus of an atom is called the

Options

A. Orbit
B. Nuclear pore
C. Axis
D. Atom

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of an Atom:**
- An atom consists of a nucleus at its center, which contains protons and neutrons. Electrons, which are negatively charged particles, revolve around this nucleus.

2. **Identifying the Path of Electrons:**
- The path that electrons take as they move around the nucleus is not random. Instead, it follows a specific pattern or trajectory.

3. **Defining the Term:**
- The fixed path along which an electron revolves around the nucleus is referred to as an "orbit." This term is used in atomic models to describe the allowed paths for electrons.

4. **Connecting to Bohr's Atomic Model:**
- According to Bohr's atomic model, electrons occupy specific energy levels or orbits around the nucleus. Each orbit corresponds to a certain energy level.

5. **Conclusion:**
- Therefore, the correct term for the fixed path along which an electron revolves around the nucleus of an atom is "orbit."

**Final Answer:**
The fixed path along which an electron revolves around the nucleus of an atom is called an **orbit**.
