In an atom, what occupies the space between the nucleus and the electrons?

• A. Empty space
• B. Quarks
• C. Protons
• D. Neutrons

Answer: (A)

Verified step by step guidance

1. Understand the structure of an atom: it consists of a dense nucleus at the center, which contains protons and neutrons, and electrons that orbit around this nucleus.
2. Recognize that protons and neutrons are located inside the nucleus, so they do not occupy the space between the nucleus and the electrons.
3. Recall that quarks are subatomic particles that make up protons and neutrons, so they are confined within the nucleus as well.
4. Consider the space between the nucleus and the electrons: this region is mostly empty, meaning it contains very little matter, allowing electrons to move around the nucleus.
5. Conclude that the space between the nucleus and the electrons is essentially empty space, which is why the correct answer is 'Empty space'.
