Each electron in an atom is in an orbital (*NOT* an orbit!!) at a specific energy level from the positive nucleus. The energy levels of these orbitals are fixed -- an electron can go from orbital 's' to orbital 'p', but it can't go halfway between these two orbitals. When an electron in an atom goes from a higher orbital to a lower one, then the atom must give off an amount of energy, that is exactly the difference in energy in the two levels.
For a hydrogen atom, these orbital levels are fixed by the fact that the angular momentum of an electron in an orbital is quantized -- ie, it comes in exact multiples, but not fractions, of a minimal amount.
What else can I help you with?
What did Niels Bohr discover?
Based on conversations with Rutherford Niels Bohr developed the Bohr-Rutherford nuclear model of the Atom. It is the one you have met in elementary school where Protons and Neutrons form a core with electrons circling in fixed orbits around the core. The orbits explained (some kind of) radiation which had hitherto been a mystery. He discovered that electrons in atoms are arranged according to the energy levels.
What experiment did Niels Bohr do?
Niels Bohr is best known for his work on the quantization of atomic structure, particularly his model of the atom which proposed that electrons orbit the nucleus in specific, quantized energy levels. While he conducted thought experiments and made theoretical contributions that shaped the field of quantum mechanics, he did not perform specific physical experiments in a laboratory setting.
What did neils bohr discover?
He proposed a description of the structure of atoms, especially that of hydrogen in 1913. The Bohr model of the atom, a radical departure from earlier, classical descriptions, was the first that incorporated quantum theory and was the predecessor of wholly quantum-mechanical models.He said that atom consists of a heavy positively charged nucleus with substantially lighter negatively charged electrons circling around it at considerable distance.He predicted that element 72 would behave as he thought. The element was named hafnium (Latin for Copenhagen).He worked with others to develop the atomic bomb, he made significant technical contributions, notably to the design of the so-called initiator for the plutonium bomb.
What was Niels Bohr famous for?
Niels Bohr was involved with many aspects of the development of Quantum Mechanics but he is best known for his theory of the Hydrogen atom. In this theory he applied Planck's concept of quantization to the dynamics of the electron in the Hydrogen atom. He concluded that the electron could only have certain energies and light emitted from Hydrogen only occured when the electron dropped from a high energy level to a lower energy level. This theory fully explained the unusual light spectrum emitted by Hydrogen, which had puzzeled scientists for years.
What did bohr do and create?
Niels Bohr (the father, not the son who also got a Nobel prize) is known for: - Nuclear models with layers explaining radiation - Contributions to quantum mechanics - Political work after WWII to put the nuclear bomb under UN control
What field of science did niels bohr work?
Niels Bohr worked in the field of physics, with a focus on atomic structure and quantum theory. He made significant contributions to the development of the theory of quantum mechanics and is best known for his model of the atom, called the Bohr model.

Who was neils bohr and what did he do?
Niels Bohr was a Danish physicist who made significant contributions to our understanding of atomic structure and quantum theory. He is best known for proposing the Bohr model of the atom, which introduced the idea of electrons orbiting the nucleus in specific energy levels. This model laid the foundation for modern quantum mechanics and earned him the Nobel Prize in Physics in 1922.
How do you describe Niels Bohr?
Niels Bohr was a Danish physicist best known for his foundational contributions to atomic structure and quantum theory. He developed the Bohr model of the atom, which introduced the idea of quantized energy levels for electrons. Bohr's work earned him the Nobel Prize in Physics in 1922, and he played a key role in the development of quantum mechanics and the philosophical implications of its principles. His legacy also includes the establishment of the Niels Bohr Institute in Copenhagen, which became a leading center for theoretical physics.
Niels bohr model?
In 1938 Bohr worked with Albert Einstein and carried out atomic research; was elected president of the Danish Academy of Science and was an advisor to the Manhattan Project, which produced the first atomic bomb.

What all did Niels Bohr invent?
Neil Bohr didn't invent he discovered that electrons in atoms are arranged according to the energy levelsAnswerNiels Bohr did not invent he discovered that electrons are arranged according to the energy levels
Which of the following statements best describes a weakness of the Bohr model of the atom?
Strengths: it shows electron shells, valence electrons, and the nucleus of an atom, how it orbits around the nucleus Weaknesses: doesn't show chemical bonding such as covalent bonds and ionic crystals
