What else can I help you with?
What was Niels Bohr's key hypothesis about the behavior of electrons in atoms that he formulated to explain the discrete pattern of atomic spectra?
Niels Bohr's key hypothesis was that electrons orbit the nucleus in specific energy levels or orbits, and they can only transition between these levels by absorbing or emitting specific amounts of energy. This hypothesis explained the discrete pattern of atomic spectra by linking the spectral lines to the energy differences between electron orbits.
What scientist proposed that electrons move around the nucleus in fixed paths?
niels bohr
How did Niels Bohr create his atom model?
Niels Bohr placed in the center of atom the atomic nucleus and electrons in movement around nucleus.
Who made the first use of quantum theory to explain the structure of atom?
Niels Bohr was the first to use quantum theory to explain the structure of the atom in his atomic model in 1913. He proposed that electrons orbit the nucleus at specific energy levels, or shells, and that energy is quantized in discrete amounts.
What was Niels Bohr theory on the periodic table?
Niels Bohr proposed that electrons orbit the nucleus of an atom in fixed energy levels or shells. He suggested that the properties of elements are determined by the number of electrons in these energy levels. This hypothesis laid the foundation for understanding the periodic table in terms of electronic structure and chemical reactivity.
What scientist said electrons move around a central nucleus?
Niels Bohr proposed the model of the atom where electrons move around a central nucleus in fixed orbits. This model helped explain the stability of the atom and the discrete energy levels of electrons.
What was Niels Bohr main contribution to chemistry?
Niels Bohr created the planetary model of the atom, including the nucleus and electrons. This, however, is not the accurate model of atoms. It is said to be the electron cloud which is most accurate
Who discovered electrons move around the nucleus in orbit patterns?
Niels Bohr
Who discovered that the electrons Move around the nucleus in orbit patterns?
Niels Bohr
Who first suggested that the electrons orbited the nucleus in fixed energy levels?
Niels Bohr first suggested that electrons orbit the nucleus in fixed energy levels in his model of the atom in 1913. This model helped to explain the stability of atoms and their emission spectra, leading to important developments in quantum mechanics.
Who portrays the planetary model of an atom?
Niels Bohr is credited with developing the planetary model of the atom, which depicts electrons orbiting the nucleus in discrete energy levels. This model helped explain the stability of atoms and the emission of light at specific wavelengths.
What was Niels Bohr's concern or question?
Niels Bohr's main concern or question was how electrons can exist in specific energy levels around the atomic nucleus without radiating energy and collapsing into the nucleus, according to classical electromagnetic theory.
