Bohr's contribution to chemistry and physics regarding atoms was a theory on the atomic structure refining rutherfords model. Atoms were already shown to exist by others. Dalton is perhaps the most influential of the early pioneers.
The observation of discrete emission spectra from elements provided the experimental evidence for Bohr's model. The only way to explain these spectra was through quantization of electron energy levels in atoms. This led Bohr to propose that electrons could only exist in specific orbits with quantized energy levels.
Niels Bohr and Max Planck are two physicists who made significant contributions to classical physics. Using Planck's work, Bohr was able to show how electrons exist in energy levels around the nucleus of an atom.
The Bohr model of the atom was the first to propose that electrons orbit the nucleus in fixed paths or energy levels. This model was proposed by Niels Bohr in 1913, and it helped to explain the stability of atoms and the emission of specific frequencies of light.

Most atoms are found in chemical compounds or bonded to other atoms, as opposed to existing in a free state. Atoms are constantly interacting with other atoms through chemical bonds to form molecules. However, certain noble gases, such as helium and neon, can exist in a relatively stable and unreactive free state.
Bohr added the concept of quantized energy levels to the atom, proposing that electrons exist in specific orbits around the nucleus, each with a specific energy level. This idea helped explain the stability of atoms and led to the development of the Bohr model of the atom.
No one invented atoms, atoms were discovered. Niels Bohr did not discover or invent the atom, he did however create a model of the atom.
Bohr wished to describe the structure of atoms.

Bohr improved Planck's theory by incorporating the concept of quantized energy levels for electrons in atoms. He proposed that electrons could only exist in certain distinct energy levels, which helped explain the stability of atoms and the emission/absorption of light in atomic spectra. This led to the development of the Bohr model of the atom.
Bohr's Atomic Theory stated that all atoms revolve around the nucleus

Niels Bohr's model of the atom proposed that electrons exist in quantized orbits around the nucleus, with each orbit corresponding to a specific energy level. Electrons can absorb or emit energy by jumping between these orbits, but they cannot exist in between these levels. This model helped explain the stability of atoms and the discrete nature of atomic spectra.
