Key Concepts

Quantized Energy Levels

Atoms have discrete energy levels that electrons can occupy, meaning electrons can only exist in specific, defined energy states. The difference between these energy levels determines the energy involved when an electron moves from one level to another.

Electron Transitions

Electron transitions refer to the movement of an electron between two energy levels within an atom. This movement changes the electron's energy, and the energy difference is either absorbed or released as a photon, depending on the direction of the transition.

Absorption of Energy

Absorption occurs when an electron transitions from a lower energy level to a higher energy level. In this process, the electron takes in energy, typically from a photon whose energy exactly matches the gap between the two levels.

Emission of Energy

Emission takes place when an electron transitions from a higher energy level to a lower energy level. The electron releases energy in the form of a photon, with its energy equal to the difference between the initial and final energy levels.
