were are the five scientific models that explain the structure of the atom
Answer (1)
Dalton’s Atomic Model (early 1800s)John Dalton proposed that atoms are indivisible solid spheres, and atoms of each element are identical in mass and properties.Thomson’s Plum Pudding Model (1897-1904)J.J. Thomson discovered electrons and suggested that atoms are spheres of positive charge with negatively charged electrons embedded like "plums in a pudding".Rutherford’s Nuclear Model (1911)Ernest Rutherford found that atoms have a small, dense, positively charged nucleus at the center with electrons orbiting around it, based on gold foil experiments.Bohr’s Model (1913)Niels Bohr proposed that electrons orbit the nucleus in fixed, quantized energy levels or shells, explaining atomic emission spectra.Quantum Mechanical Model (1920s onward)Developed by Schrödinger, Heisenberg, and others, this model treats electrons as wave-like particles occupying orbitals—regions of probability rather than fixed paths.These models show the evolution of atomic theory from indivisible particles to a complex structure with a nucleus and electron clouds.
