**Understanding Atomic Structure: A Multiple-Choice Question Example**

In the study of atomic structure, it's crucial to understand the characteristics and distribution of subatomic particles within an atom. Consider the following question to test your knowledge on this topic:

---

**Which statement is true?**

**a.** Protons and neutrons have the same mass, but electrons are much lighter. All three particles are evenly distributed throughout the atom. Protons are positively charged, neutrons are neutral, and electrons are negatively charged.

**b.** Protons and neutrons have the same mass, but electrons are much lighter. Protons and neutrons are in the nucleus, and electrons occupy energy levels in the electron cloud. Protons are positively charged, neutrons are neutral, and electrons are negatively charged. ⬤

**c.** Protons, neutrons, and electrons have equal mass and are evenly distributed throughout the atom. Protons are positively charged, neutrons are neutral, and electrons are negatively charged.

**d.** Protons and neutrons have the same mass, but electrons are much lighter. Protons and neutrons are in the nucleus, and electrons occupy energy levels in the electron cloud. Protons are positively charged, neutrons are neutral, and electrons are negatively charged.

---

In this multiple-choice question, the correct answer is indicated by the filled circle next to it. Here's a breakdown of why option **b** is correct:

- **Protons and Neutrons:** Both particles have approximately the same mass, significantly heavier than electrons.
- **Electrons:** These have much less mass compared to protons and neutrons.
- **Distribution:** Protons and neutrons reside in the nucleus of the atom. Electrons are found in the electron cloud, occupying specific energy levels.
- **Charges:** Protons are positively charged, neutrons are neutral, and electrons carry a negative charge.

Understanding these basic principles is vital for studying further topics in chemistry and physics, such as atomic interactions, chemical bonding, and electrical conductivity.
