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

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

Answer: (B)

Verified step by step guidance

1. Understand the structure of an atom: it consists of a nucleus containing protons and neutrons, and electrons that exist outside the nucleus.
2. Recall that electrons are not located inside the nucleus but are found in regions around the nucleus called orbitals, which are areas where there is a high probability of finding an electron.
3. Recognize that orbitals are defined by quantum mechanics and represent the spatial distribution of electrons, rather than fixed paths or surfaces.
4. Eliminate incorrect options: electrons are not inside the nucleus, not randomly distributed throughout the atom, and not attached to the surface of the nucleus.
5. Conclude that electrons are most likely to be found in orbitals surrounding the nucleus, which is the correct conceptual understanding of electron location in an atom.
