Explain how the wavelengths of light emitted by an atom provide information about electron energy levels?
We know what a wavelength is, and when we apply the term to the phenomenon of electron energy levels, something amazing happens. Let's review by looking at atomic structure for a moment and take off from there.
We know that electrons form up in orbitals and shells around an atomic nucleus. These orbitals are defined as energy levels, and an electron is said to be in a given energy level. When electrons get just the right amount of energy, they can "jump" to a higher energy level. There are places that they cannot go, but there are other places that are "just right" for an electron from that particular starting energy level. A specific quantity of energy (a quantum, perhaps) is the key to electrons changing energy levels.
If an electron is "bumped" to a higher energy level because it has "accepted" a packet of energy that is just right, it moves up to that energy level. But it cannot stay there, so it "falls back" to where it came from. In returning to its original energy level, it must "give up" the exact amount of energy that it took to move up. This specific amount of energy translates into radiated electromagnetic energy of a given wavelength or frequency. And each wavelength corresponds to a given amount of energy. Let's apply this and see what happens.
Should we consider a bunch of atoms of a given kind, they will have a specific electron structure. The electrons of these atoms "live" in given energy levels. If we excite these atoms with the right amounts or quanta of energy, the electrons that will only respond to that amount of energy will move to a higher energy level. Then the electrons will return to their original levels, giving up that wavelength of energy when they drop down. If the wavelength of electromagnetic energy is in the optical band, visible light will appear. The atoms will "glow" at a specific color associated with the wavelength of the energy that is released when those electrons return to their original energy levels.
If those atoms in our experiment are a gas and we apply sufficient voltage, the gas atoms will ionize and the gas will glow. Electrons are accepting energy quanta, are moving to higher energy levels, and are then returning to their original energy levels by releasing visible light of a given color. Electron energy levels are directly related to wavelengths of electromagnetic radiation.

What measures the exact frequency of the light emitted when an electron changes levels?
Spectrometer is used to measure the exact frequency of the light emitted when an electron changes levels. It separates the different wavelengths of light to determine their frequencies accurately.
Why do you think are there different color emitted?
There different colors emitted
How the wavelengths of light emitted by an atom provide information about electron energy levels?
First, calculate the energy of the photon by using the wave length and then see which the energy differences between electon levels. If it is equal, then it is the right transition The energy of a photon is proportional to its frequency
What particle is emitted when Na-20 decays to Ne-20?
When Na-20 decays to Ne-20, it emits a beta-minus particle, which is essentially an electron. This is because in beta-minus decay, a neutron is converted into a proton, releasing an electron and an antineutrino.
Why is a shorter wavelength of light emitted when an electron falls from n4 to n1 than when an electron falls from n2 to n1?
When an electron falls from n4 to n1, it releases more energy because it is transitioning between high energy states. This higher energy transition corresponds to a shorter wavelength of light being emitted, according to the energy of the photon being inversely proportional to its wavelength. In contrast, when an electron falls from n2 to n1, the energy released is less, resulting in a longer wavelength of light emitted.
What measures the exact frequency of the light emitted when an electron changes levels?
Spectrometer is used to measure the exact frequency of the light emitted when an electron changes levels. It separates the different wavelengths of light to determine their frequencies accurately.
Why does hydrogen emit different wavelengths of light than mercury?
Hydrogen emits different wavelengths of light than mercury because they have different electron configurations. In hydrogen, the electron transitions occur at specific energy levels determined by the electron orbitals, leading to discrete spectral lines. On the other hand, mercury has more complex electron transitions due to its larger number of electrons and energy levels, resulting in a broader range of wavelengths emitted.
Why do you think are there different color emitted?
There different colors emitted
How many photon are emitted when an electron moves from n equals 6 to n equals 3?
6 - 3 = 3 In a sequence cascade there would be three photons emitted; one for every level and three different wavelengths depending on the atom. If the drop is from 6 to 3 then only one photon is emitted.
How long are the wavelengths of radiation emitted by Earth are?
The wavelengths of radiation emitted by Earth are primarily in the infrared spectrum, ranging from about 5 to 100 micrometers. This is known as terrestrial or thermal radiation, and it is a form of heat energy emitted by the Earth's surface and atmosphere.
Is radioactive decay an electron?
No. An electron may be emitted in some cases, though.
What is emitted by an atom as a result of electron capture?
After electron capture a neutrino is released.
Why would the absorption of each element have lines in the same places as its emission spectrum?
The absorption spectrum of an element features lines at the same wavelengths as its emission spectrum because both processes involve the same energy transitions between electron energy levels. When an electron absorbs energy, it moves to a higher energy level, resulting in the absorption of specific wavelengths of light. Conversely, when an electron falls back to a lower energy level, it releases energy in the form of light at those same wavelengths. This correspondence between absorbed and emitted wavelengths is a fundamental characteristic of atomic structure.
One indicator that electrons in atoms are limited to specific energy levels is that?
light emitted from excited atoms occurs only at specific wavelengths
What is the electron emitted from the atom called?
the gamma ray.
How did Bohr explain the line spectrum of hydrogen?
The difference in energy between the energy levels determines color of light emitted when an electron moves from one energy level to another.
What causes the difference in colors emitted by different colors?
different wavelengths from different colours
