Energy Levels
Energy levels in atomic structure refer to the fixed distances from the nucleus where electrons can exist. Think of these levels as "orbits" that hold electrons at certain energies. An electron can jump between these levels by absorbing or releasing energy, such as when it absorbs light. Lower levels have less energy and are closer to the nucleus, while higher levels are farther away and have more energy. This organization helps explain how atoms interact, bond, and form the matter around us.

Energy levels refer to the specific states of energy that electrons can occupy within an atom. Think of them like the floors of a building, where each floor has a defined height. Electrons can move up or down between these levels, absorbing or releasing energy in the form of light or heat. Higher energy levels mean the electron is further from the nucleus, while lower levels are closer. This concept helps explain various phenomena in chemistry and physics, such as why atoms emit specific colors of light when heated or how they interact in chemical reactions.
