In an atom, where are electrons most likely to be found?

• A. Randomly distributed throughout the atom
• B. Attached to the surface of the nucleus
• C. Inside the nucleus with protons and neutrons
• D. In orbitals surrounding the nucleus

Answer: (D)

Verified step by step guidance

1. Understand that electrons are subatomic particles with a negative charge that exist in atoms.
2. Recall that the nucleus of an atom contains protons and neutrons, which are much heavier and positively charged (protons) or neutral (neutrons).
3. Recognize that electrons are not located inside the nucleus or attached to its surface; instead, they occupy regions of space around the nucleus called orbitals.
4. Orbitals are defined by quantum mechanics and represent the probability distribution where an electron is most likely to be found, rather than fixed paths.
5. Therefore, electrons are most likely found in these orbitals surrounding the nucleus, not randomly distributed or inside the nucleus.
