Verified step by step guidance1
Understand that the question is asking for the term that describes the region in an atom where an electron is most likely to be found.
Recall that electrons in an atom are arranged in different regions based on their energy and probability of location.
Know that an 'energy level' refers to the fixed energies an electron can have, often represented by principal quantum numbers (n = 1, 2, 3, ...).
Recognize that the 'valence shell' is the outermost energy level of an atom that contains electrons involved in chemical bonding.
Identify that an 'orbital' is a more specific region within an energy level where there is a high probability of finding an electron, which matches the definition given in the question.
