Chadwick discovered the neutron; he isn't the author of an atomic model.
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.
Bohr formulated new explanation and theories to remove Rutherford defect in Rutherford atomic model thats why Bohr atomic model is better than Rutherford atomic model.
The modern atomic model is based on quantum mechanics.
Niels Bohr propose a planetary model for the atomic nucleus.
An atomic model of Dalton doesn't exist; the model of Thomson was called plum pudding model.

The atomic model cannot be extremely accurate.
Chadwick's theory, which proposed the existence of the neutron to explain atomic mass discrepancies, faced challenges regarding its implications for atomic structure and stability. While it successfully identified neutrons as neutral particles within the nucleus, it did not fully account for the forces at play in atomic nuclei, leading to questions about nuclear stability and the behavior of isotopes. Additionally, later developments in quantum mechanics and particle physics revealed more complexities in nuclear interactions that Chadwick's initial model did not address.
Bohr formulated new explanation and theories to remove Rutherford defect in Rutherford atomic model thats why Bohr atomic model is better than Rutherford atomic model.

Discover of the {Neutron}.In 1932 the English physicist James Chadwick discovered the neutron. He found it to measure slightly heavier than the proton with a mass of 1,840 electrons and with no charge (neutral). The proton-neutron together, received the name, "nucleon."The existence of neutrons explained why atoms are heavier than the total mass of their protons and electrons.Thus for hydrogen, the Nuclear "circle" consisted of p's(protons),n's(neutrons),and surrounded be roaming e's(electrons).According to the modern atomic model,The central nucleus consists of protons and neutrons. It containing almost all the mass of the atom.the nucleus of an atom is very small compared to the size of the atom.the electrons are orbiting outside the nucleus in the electron shells.the electrons are moving in electron shells at a very high speed and we cannot determine the position of the electrons at a particular time.
Niels Bohr propose a planetary model for the atomic nucleus.
The atomic model includes protons, electrons and neutrons.
An atomic model from Dalton doesn't exist.
An atomic model of Dalton doesn't exist; the model of Thomson was called plum pudding model.
An atomic model from Jabir Ibn Hayyan is not known.
Niels Bohr is considered the founder of the modern atomic model.
