Multiple Choice

Electrons are found in ______ around the nucleus.

Electrons occupy regions surrounding the nucleus, held near it by the attraction to positively charged protons. In the simple model, they reside in orbitals or electron shells around the nucleus, forming what we call the electron cloud. The nucleus itself contains protons and neutrons, so electrons are not inside those particles or inside the nucleus. That’s why the description “in orbit around the nucleus” is the best way to express where electrons are located.
