Chapter 1 Atomic Structure & Chemical Bonding 5 Electrons reside in shells and orbitals The arrangement of electrons around the atomic nucleus is complex, and electrons do not simply orbit the nucleus as a planet would orbit a star. Broadly speaking, electrons are located in concentric shells that surround the nucleus.
