Quantum Model

Schrödinger, Heisenberg, Dirac — 1920s No orbits. No fixed paths. Just probability. The Quantum Mechanical Model replaced the clean planetary image with something stranger and more accurate: electron clouds — regions of space where an electron is likely to be found, never precisely located. Built from the work of Schrödinger, Heisenberg, and Dirac, this is the model that actually predicts chemical behavior, spectral lines, and bonding with precision. It's the atom as physics genuinely understands it — uncertain by nature, and more powerful for it.
