When an electron in an atom moves from a lower energy state to a higher state?
The electron absorbs energy and moves to a higher energy level. This process is known as excitation. The electron can then release the absorbed energy by emitting a photon and returning to a lower energy state.
The line emission spectrum of an atom is caused by the energies released when electrons?
The line emission spectrum of an atom is caused by the energies released when electrons fall from high energy level. It goes down to a low energy level and the extra energy it had from higher level is released as light.
When the light is bluer the each photons contains?
When light is bluer, it means it has a higher frequency. Each photon carries energy, and the energy of a photon is directly proportional to its frequency. Therefore, in bluer light, each photon contains higher energy compared to redder light.
Why do atoms emit only certain wavelengths of light?
The electrons in an atom's "electron shell" all have specific energy levels. If you add energy to an atom, the atom will absorb a specific amount of energy, and the electron will jump up to a higher energy level. Each different element has its own energy levels, and it can only absorb energy in specific amounts. (When you add a lot of energy to the atom, the atom becomes ionized, as one or more electrons absorb enough energy to break free of the atom completely, leaving the atom with an unbalanced positive electrical charge.) When those "excited" or jumped-up electrons release the energy, the electron drops back to its previous level, and the atom (or more specifically, the electron) emits a photon, which is a particle of light. Each photon has a frequency or energy that is distinctive to the element and the energy level. Electrons cannot have intermediate energies; they absorb and release exact "packets" or "quanta" of energy. This is how a mass spectrometer works; the operator ionizes a sample of the material that he wants to analyze, and watches the resulting spectrum. Each wavelength of light emitted by the sample corresponds to one specific element.
Spectral lines produced from the radiant energy emitted from excited atoms are thought to be due to the movements of electrons?
That’s correct. Spectral lines are produced when electrons in atoms move between energy levels. When an electron drops to a lower energy level, it emits a photon of a specific energy corresponding to a specific wavelength of light, creating spectral lines in the emitted light spectrum.
Can you explain why an electron's energy increases when it absorbs a photon and also describe what happens to the photon in this process?
When an electron absorbs a photon, its energy increases because the photon transfers its energy to the electron. The photon ceases to exist as a discrete particle and its energy is absorbed by the electron, causing it to move to a higher energy level.
When an electron drops to a lower energy level what is the energy of a photon released?
The energy of the photon is the same as the energy lost by the electron
The light bearing packet of energy emitted by an electron is called a?
A packet of light energy is called a photon.
How can a photon be destroyed or created?
A photon can be created when an electron transitions to a lower energy level and emits a photon. Conversely, a photon can be absorbed and "destroyed" when it is absorbed by an electron, causing the electron to transition to a higher energy level.
If you make the electron jump downward then return it to the outer ring what do you notice about the photon released or absorbed?
When an electron jumps downward to a lower energy state in an atom, it releases energy in the form of a photon which is emitted. When the electron returns to the outer ring, it absorbs energy in the form of a photon. The energy of the photon absorbed is equal to the energy of the photon released during the downward jump.
When an electron in atom changes energy states a photon is emitted If the photon has a wavelength of 550 nm how did the energy of the electron change?
The energy of the electron decreased as it moved to a lower energy state, emitting a photon with a wavelength of 550 nm. This decrease in energy corresponds to the difference in energy levels between the initial and final states of the electron transition. The energy of the photon is inversely proportional to its wavelength, so a longer wavelength photon corresponds to lower energy.
When an electron drops from a higher energy state to a lower energy state?
When an electron drops from a higher energy state to a lower energy state, it emits electromagnetic radiation in the form of a photon. This process is known as atomic emission, and the energy of the emitted photon corresponds to the energy difference between the two electron states.
If an electron is in an excited state it must lose energy when it falls to a lower state. What happens to the energy that is lost?
The energy that is lost when an electron falls to a lower state is emitted as a photon of light. This process is known as photon emission, and the energy of the emitted photon corresponds to the energy difference between the initial and final states of the electron.
What does an electron do when a photon is released by an atom?
When an electron releases a photon, it moves to a lower energy level within the atom. This process is known as an electron transition. The released photon carries the energy difference between the initial and final energy levels of the electron.
When an electron drops to a lower energy level what is the energy of the photon released?
The energy of the photon is the same as the energy lost by the electron
When sunlight excites electrons how do the electrons change?
Depending on the energy (frequency) of the specific photon hitting the electron, one of three events happens: nothing, the electron is excited, or the electron leaves the atom. If the energy of the photon very high, the electron can absorb the energy and escape the nucleus' pull. This is called ionization. If the energy of the photon lines up with the energy spacing in the atoms energy levels, the electron will move to a higher energy state, becoming excited. The electron then returns to its original energy level, releasing the energy as light. If the energy of the photon does not fall into one of these categories, the electron does not interact with it. In terms of actually changing the electron, it only changes in energy, not any other property.
How does an electron must move in order to release a photon of light?
An electron must move from a higher energy level to a lower energy level within an atom in order to release a photon of light. This process, known as electron transition, results in the emission of light energy in the form of a photon.
