Electron Configuration and Atomic Models

These flashcards cover key concepts related to electron configuration, atomic models, and analytical techniques in chemistry.

Electron Configuration

The arrangement of electrons around the nucleus of an atom.

Valence Electrons

Electrons in the outermost shell of an atom that determine its chemical behavior.

Bohr Model

A model of the atom where electrons revolve around the nucleus in fixed orbits corresponding to specific energy levels.

Emission Spectra

The spectrum of light emitted by an element when electrons transition between energy levels.

Ionisation Energy

The energy required to remove an electron from an atom.

Subshells

Energy levels within a shell, labeled as s, p, d, and f, where electrons reside.

Orbitals

Regions of space within subshells where electrons are likely to be found.

Schrödinger Model

A model of the atom that describes electrons as wave-like phenomena occupying three-dimensional spaces.

Flame Tests

A technique used to identify elements based on the characteristic colors produced when metals are heated.

Electron Transition

The movement of an electron from one energy level to another, causing energy to be emitted or absorbed.
