Hydrogen Atom Wave Function

Definition

The hydrogen atom wave function is a mathematical description of the quantum state of the electron in a hydrogen atom, determined by the solutions to the Schrödinger equation. This wave function provides information about the probability distribution of finding the electron at various points around the nucleus, reflecting the atom's discrete energy levels and spatial characteristics. It highlights the dual wave-particle nature of electrons and plays a crucial role in understanding atomic structure and behavior.
