inspired by the Ancient Greek concept of atoms (from the Greek word 'atomos,' meaning indivisible), posits that atoms are indivisible, that all atoms of a given element are identical, and that compounds consist of combinations of different types of atoms., He discovered electrons, which he referred to as 'corpuscles,' earning a Nobel Prize for his work. His model depicts it as consisting of electrons dispersed within a positive charge cloud.., He directed positively charged alpha particles at a thin gold foil. Most of the particles went through without much change, but some bounced off at sharp angles. This showed that atoms are mostly empty space, with the positive charge concentrated in the center, called the nucleus., He updated Rutherford's atomic model by proposing that electrons orbit the nucleus in fixed paths with specific sizes and energy levels. In this model, electron energy is quantized, meaning electrons cannot have energy values between these fixed levels., He proposed that electrons do not travel in fixed paths around the nucleus but move in waves. He stated that we cannot determine an electron's exact location; instead, we use 'clouds of probability' called orbitals to indicate where an electron is likely to be found.
