No, Bohr did not prove that atoms exist. However, he made significant contributions to the atomic theory by proposing a model that explained the stability of atoms and the emission of spectral lines by electrons. His model laid the foundation for our current understanding of atomic structure.

What experimental evidence led to bohr to believe that electrons can posses only specific amounts of energy?
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.
What is borh planks theory?
Bohr's theory is a model of the atom proposed by Niels Bohr in 1913. It suggests that electrons orbit the nucleus in specific energy levels, or shells, rather than in continuous orbits. This theory helps explain the stability of atoms and the emission of discrete spectral lines.
Which model of the atom first proposed that electrons orbit the nucleus?
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.
What scientist proposed that electrons move around the nucleus in fixed paths?
niels bohr
Is all the atoms cannot exist in free state?
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.
What did bohr add to the atom?
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.
Did Niels Bohr invent atoms?
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.
What was Niels Bohr's aim in his atomic theory?
Bohr wished to describe the structure of atoms.
Who said atoms constantly move.?
Bohr
How did Bohr improve Planck's theoory?
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.
What was Bohr's Aomic Theory?
Bohr's Atomic Theory stated that all atoms revolve around the nucleus
What is Bohr's atomic model of atoms based on?
Hydrogen
Who discovered All matter is made of atoms?
bohr
What experimental evidence led to bohr to believe that electrons can posses only specific amounts of energy?
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.
What discovery demostrated that atoms are mostly empty space?
bohr
Who said that atoms are made or a single material?
bohr said this
What were the rules about Niels Bohr electrons?
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.
