This is the energy formula for hydrogen Ejn=(-13.6eV/n2)*[1+(α2/n2)*((n/(j+0.5))-0.75)] where n is the energy level (n=0 is the ground state), α is the fine-structure constant, and j and the eigenvalue of angular momentum (j=1 +/- 0.5). This can be verified experimentally because if the electron in hydrogen is excited to n=2 then de-excites to n=1 a photon of energy E2-E1=Ephoton will be released and is we measure the energy of this photon by Ephoton=h*f, where h is Planck's constant and f is frequency.

Quantized energy levels are supported by experimental observations such as atomic absorption and emission spectra, where only specific wavelengths of light are absorbed or emitted by the atoms due to transitions between quantized energy levels. Additionally, phenomena such as the photoelectric effect, where electrons are ejected from a material by absorbing photons of specific energies, also provide evidence for the quantization of energy levels. These observations align with the predictions of quantum mechanics, which describes the behavior of particles at the atomic and subatomic level.

∙ 9y agoThe bright line spectrum shows the energy levels in an atom are quantized. The different lines on the hydrogen atom are visible going from an excited state back down to the ground state. These lines have different colors and each color represents the different levels the electrons have fallen from.

∙ 12y agoThere are specific energy values which are allowed for the electron in the hydrogen atom. The evidence for this lies in the way in which the line spectra of the hydrogen atom only shows certain wavelengths. These wavelengths correspond to the specific transition states of the electron between its fixed energy states within the atom.

What spectrum is evidence for quantized change?
The electromagnetic spectrum provides evidence for quantized changes in energy levels of atoms. This is seen in the emission or absorption of specific discrete frequencies of light, which is a result of electrons jumping between quantized energy levels within the atom. This phenomenon is described by quantum mechanics.
What are Energy levels where only certain values are allowed called?
Energy levels where only certain values are allowed are called quantized energy levels. This concept is central to quantum mechanics, where particles like electrons can only occupy specific energy levels in an atom.
Which property shows that electrons are quantized?
Each electron has its own "address."
Which of the following is a quantized condition?
Food on shelves in a refrigerator
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 are quantized energy levels?
Quantized energy levels refer to the specific energy values that a system can possess in discrete steps, rather than continuously. This concept is often seen in quantum mechanics, where particles can only exist at specific energy levels defined by specific quantum numbers. These quantized energy levels play a crucial role in determining the behavior and properties of atoms and molecules.
What are Energy levels where only certain values are allowed called?
Energy levels where only certain values are allowed are called quantized energy levels. This concept is central to quantum mechanics, where particles like electrons can only occupy specific energy levels in an atom.
What are the Three examples of properties that are quantized at the scale of an electron?
Electrical charge is quantized. (negative in an electron, as an electron has exactly -1 fundamental unit of charge) The other two would be the energy levels in the atoms and the emitted energy.
What is the explanation for the discrete lines in atomic emissions spectra?
e- absorb energy and move to an orbital of higher energy. Falls back down to lower energylevels releasing the energy. The lines result from the fact that e-'s can only have discrete/quantized energy levels, they cannot have intermediate energy levels.
How does the flame test provide support for quantized energy levels?
The flame test shows that elements emit characteristic colors when heated, based on the energy levels of their electrons. The specific colors observed correspond to the specific energy differences between electron orbital transitions, supporting the idea of quantized energy levels in atoms. Different colors emitted indicate distinct energy levels for each element.
Is every kind of energy quantized?
Planck formulated an equation for energy quanta, which is quantized into E=hf (where E is energy, h is Planck's constant: 6.626x10-27 , and f is frequency) to obtain his own exact radiation formula. This also happened to disprove the theory of the Ultraviolet Catastrophe, which is where classical physics failed.
What do electrons do in Bohr's model of atoms?
In Bohr's atomic model, electrons are in specific orbitals (NOT orbits), which are at specific energy levels. An electron can go directly from one orbital to another, but it can never be in-between any two orbitals. The energy level of these orbitals is specified by angular momentum being quantized.
Who developed the idea of electron shell?
Niels BohrNiels Bohr proposed the first model of the atom with distinct energy levels with quantized energies. He proposed this theory based on the spectra of atoms and ions.
Bohr used the emission spectrum of hydrogen to support his idea that?
Each energy level corresponds to an exact amount of energy needed by the electron to orbit the nucleus. Transitions from a higher energy level to a lower energy level correspond to the difference in the energy needed for an electron to occupy those two energy levels. This difference creates the emission spectrum.
What is the difference between electronic band and subband in solid state physics?
When energy is quantized, each of the levels corresponds to one band. But each level can depend upon the total velocity or position. If one energy level depends on each of coordinates, each coordinate can give a contribution to the total energy. This represents a subband.
Which type of diagram shows the number of trophic levels an ecosystem supports?
A biomass pyramid.
