Where do electrons exist in atoms?

• A. Inside the nucleus
• B. Far outside the nucleus, orbiting it
• C. Only in the nucleus's outer shell
• D. They are not part of atoms

Answer: (B)

Electrons exist in regions around the nucleus, not inside it. The nucleus contains protons and neutrons, and the positive charge there attracts the negatively charged electrons, keeping them in the space surrounding the nucleus. In basic terms, electrons occupy energy levels or shells around the nucleus, so they’re described as being far outside the nucleus and effectively orbiting it. They are not part of the nucleus, and there isn’t just a single outer shell—electrons can occupy multiple levels.
