Verified step by step guidance

Observe the image: It depicts an atom with a nucleus at the center and electrons orbiting around it in concentric circles.

Identify the concentric circles: These circles represent different energy levels or shells where electrons reside.

Understand the term 'shell': In atomic structure, a shell is a group of atomic orbitals with the same principal quantum number, n, representing the energy level of electrons.

Relate the image to the term 'shell': The electron shown in the image is located on one of these concentric circles, which corresponds to a shell.

Conclude the description: The term 'shell' best describes the electron's location in the image, as it is situated on a specific energy level or shell around the nucleus.
