J.J. Thomson is credited with discovering electrons in 1897 through his cathode ray tube experiments. Thomson's work paved the way for the understanding of atomic structure and the development of the atomic model.
Niels Bohr is the scientist whose model of the atom is now accepted as the most accurate atomic structure. His Bohr model, which incorporates quantized energy levels and elliptical orbits for electrons, was a significant advancement in understanding atomic structure.
Ernest Rutherford was the first scientist to describe an atomic model in which most of the atom is empty space. His model proposed that atoms have a dense positive nucleus surrounded by orbiting electrons in empty space.
The plum pudding model was proposed by J.J. Thomson in 1904, before the discovery of the atomic nucleus. It suggested that atoms were composed of positively charged substance with electrons embedded within it like plums in a pudding. It was later replaced by the Rutherford model when the nucleus was discovered.
Chadwick's atomic model, proposed by James Chadwick in 1932, introduced the concept of the neutron in the atomic nucleus. This model helped to explain the stability of the nucleus and resolved some of the issues with the Rutherford atomic model, specifically the absence of sufficient mass in the nucleus to account for its positive charge. The discovery of the neutron as a neutral particle in the nucleus was a significant advancement in our understanding of atomic structure.

John Dalton developed the first modern atomic theory in the early 19th century, proposing that elements are made up of tiny, indivisible particles called atoms. Later, Ernest Rutherford's gold foil experiment in 1911 led to the discovery of the nucleus and the planetary model of the atom.

Some of the key scientists involved in the development of atomic theory include John Dalton, who proposed the atomic theory in the early 19th century, J.J. Thomson, who discovered the electron, Ernest Rutherford, known for his gold foil experiment that led to the discovery of the nucleus, and Niels Bohr, who developed the planetary model of the atom.
Ernest Rutherford's famous gold foil experiment led to the discovery of the atomic nucleus. This discovery changed the atomic model by replacing the plum pudding model with the planetary model, where electrons orbit a central nucleus. Rutherford proposed that the nucleus contained positively charged protons while the electrons orbited around it.
Chadwick's discovery of the neutron in 1932 significantly altered the atomic model by introducing a neutral particle within the nucleus, alongside protons. This discovery explained the existence of isotopes—atoms of the same element with different masses—due to variations in neutron numbers. It also helped clarify the overall structure of the atom, leading to a more comprehensive understanding of atomic stability and nuclear reactions. Consequently, the atomic model evolved from a simplistic view to a more complex structure, incorporating both protons and neutrons in the nucleus.
The scientist who developed the atomic theory of matter was John Dalton. He proposed that matter is made up of indivisible particles called atoms that combine in specific ratios to form different compounds.
Niels Bohr discovered that atoms have distinct energy levels in 1913, while working on his model of the hydrogen atom. This discovery laid the foundation for our current understanding of atomic structure and how electrons move within atoms.
There are lots of scientist out their. Three scientist that I know are Democritus's model name is Atomos. Another is Erin Schrodinger and Werner Heisenberg model name is the charged cloud model. Finally, I know Ernest Rutherford's model name is the neon atom.
