10 Αυγ 2022 · The electron shells are labeled K, L, M, N, O, P, and Q; or 1, 2, 3, 4, 5, 6, and 7; going from innermost shell outwards. Electrons in outer shells have higher average energy and travel farther from the nucleus than those in inner shells.

Electron Shells. In very simple terms an electron shell is the outside part of an atom that surrounds the atomic nucleus. The shells are orbital paths that are followed by electrons around the nucleus. Like everything in chemistry, electrons like to follow the path of least resistance.
When drawing orbital diagrams, we include empty boxes to depict any empty orbitals in the same subshell that we are filling. Carbon (atomic number 6) has six electrons. Four of them fill the 1s and 2s orbitals. The remaining two electrons occupy the 2p subshell.
30 Ιαν 2023 · Bohr diagrams show electrons orbiting the nucleus of an atom somewhat like planets orbit around the sun. In the Bohr model, electrons are pictured as traveling in circles at different shells, depending on which element you have.
Describe the structure of shells and subshells in multi-electron atoms, and relate them to the observed emission spectra. Explain the Bohr-Sommerfeld model. For an electron in a given subshell, determine the quantum numbers, and explain your answer.
