Good conductors have many loosely bound

Options

A. atoms
B. protons
C. molecules
D. electrons

Answer

**Step-by-Step Solution:**

1. **Understanding Conductors:**
- Conductors are materials that allow the flow of electric current. This flow is primarily due to the movement of charged particles, which in most cases are electrons.

2. **Identifying the Role of Electrons:**
- In good conductors, the electrons are not tightly bound to their respective atoms. This means they can move freely when an electric field is applied.

3. **Analyzing the Options:**
- The question provides four options: atom, proton, molecule, and electron. We need to determine which of these has loosely bound particles in good conductors.

4. **Evaluating Each Option:**
- **Option 1: Atom** - Atoms are made up of protons, neutrons, and electrons. While they contain electrons, the term "atom" does not specifically refer to the loosely bound particles that facilitate conduction.
- **Option 2: Proton** - Protons are positively charged particles found in the nucleus of an atom. They are not involved in the conduction of electricity as they are not free to move.
- **Option 3: Molecule** - Molecules are formed when two or more atoms bond together. While some molecules can conduct electricity, they do not represent the loosely bound particles in conductors.
- **Option 4: Electron** - Electrons are negatively charged particles that can move freely in a conductor. In good conductors, these electrons are loosely bound, allowing them to flow easily when an external voltage is applied.

5. **Conclusion:**
- Since good conductors have many loosely bound electrons that can move freely to conduct electricity, the correct answer is **Option 4: Electron**.
