Concept Introduction: Protons, neutrons, and electrons are the three subatomic particles that make up an atom. The idea of energy levels surrounding the nucleus served as the basis for Bohr's model. The atomic model was the earliest and most widely accepted. Quantum numbers, the Heisenberg uncertainty principle, and other ideas form the foundation of the quantum mechanical paradigm.
The position and energy of the electrons in an atom at a specific energy level are represented by quantum numbers. The arrangement of electrons in various energy levels of an atom is known as its electronic configuration.
