Key Concepts

Electron Configuration

Electron configuration refers to the arrangement of electrons in the atomic orbitals of an atom. It details how electrons populate orbitals based on energy levels, following the Aufbau principle, Pauli exclusion principle, and Hund's rule, which collectively explain the order and manner in which electrons are added to an atom's orbitals.

Orbital Diagram

An orbital diagram is a pictorial representation of the electron configuration of an atom. It illustrates the occupancy of orbitals using boxes (or lines) to represent orbitals and arrows to depict electrons and their spins, providing a clear visual summary of the distribution and relative energies of electrons in an atom.

Absorption of Radiation and Electron Excitation

Absorption of radiation involves an electron absorbing energy in the form of light (or photons) and transitioning from a lower-energy orbital to a higher-energy orbital. This process is key to explaining how electrons in atoms become excited when they absorb photons of specific wavelengths, leading to temporary excited states.

Energy Transitions and Wavelengths

Energy transitions refer to the changes in energy levels that electrons undergo when they absorb or emit radiation. The specific wavelengths of radiation absorbed correspond to the energy differences between the electron's initial and final orbitals, with longer wavelengths generally corresponding to lower-energy transitions. This concept is essential for understanding which electronic excitations occur under different energy inputs.
