Electron energy levels refer to the discrete energy states that electrons can occupy in an atom, determined by the quantized nature of their wavefunctions. These levels are crucial for understanding atomic structure, chemical bonding, and the emission or absorption of photons during electronic transitions.

Electron energy levels

discrete energy states

Energy states refer to the discrete levels of energy that a physical system, such as an atom or molecule, can have. These states are determined by quantum mechanics and are crucial for understanding phenomena like electron configurations, spectral lines, and chemical reactions.

energy states

quantized nature

Wavefunctions are mathematical descriptions of the quantum state of a system, encapsulating all the information about a particle's position and momentum. They are central to quantum mechanics, with their squared magnitude representing the probability density of finding a particle in a given space.

wavefunctions

Atomic structure refers to the arrangement of subatomic particles—protons, neutrons, and electrons—within an atom, which determines its chemical properties and behavior. Understanding atomic structure is fundamental to fields like chemistry and physics, as it explains the periodic table, bonding, and the nature of matter itself.

atomic structure

Chemical bonding is the process by which atoms combine to form molecules and compounds, driven by the attainment of a more stable electronic configuration. The main types of chemical bonds are ionic, covalent, and metallic, each involving different mechanisms of electron sharing or transfer.

Emission of photons

absorption of photons

Electronic transitions involve the movement of electrons between different energy levels within an atom or molecule, typically induced by the absorption or emission of photons. These transitions are fundamental to understanding phenomena such as spectroscopy, chemical reactivity, and the electronic properties of materials.
