How is the light of an emission spectrum of an element produced?
The light of an emission spectrum is produced when electrons in an atom jump from higher energy levels to lower energy levels, emitting photons of specific energies. Each element emits light at characteristic wavelengths and produces a unique emission spectrum, which can be used to identify the element.
What causes photons to be emitted from excited atoms?
The energy difference, between two energy levels, is emitted as a photon, when the electron "falls down" to a lower energy level.
Why do cations emit colors when heated in a Bunsen burner flame?
Transitions between electronic energy levels release electromagnetic radiation corresponding to the energy difference between the levels. The heat promotes the electrons to the higher level; when they drop back down to the lower level a specific color of light is emitted.
When 10 electrons drop from fifth to second energy level?
When 10 electrons drop from the fifth to the second energy level, energy in the form of photons is emitted. The energy of the emitted photon is equal to the difference in energy levels between the initial and final states of the electrons. This process is known as photon emission or de-excitation.
What is the wavelength of the photon emitted when a hydrogen atom goes from the second energy level to the first energy level?
The wavelength of the photon emitted can be calculated using the Rydberg formula: 1/wavelength = R(1/n1^2 - 1/n2^2), where R is the Rydberg constant, n1 is the initial energy level (2 in this case), and n2 is the final energy level (1 in this case). Plugging in the values gives the wavelength of the photon emitted.
Why do different wavelengths refract differently when entering glass?
Different wavelengths of light refract differently when entering glass because they interact differently with the glass's molecules. Each wavelength corresponds to a different frequency and energy level, which affects how the light is absorbed and re-emitted by the glass, causing variations in refraction. This phenomenon is known as dispersion.
What causes specific lines to appear in a line spectrum?
There are a couple of things that cause specific lines to appear in a line spectrum. Two of these things are density and wavelength.
What are the wavelengths of hydrogen?
The hydrogen spectrum consists of several series of spectral lines, each corresponding to a different electron transition. The Lyman series, which corresponds to transitions to the n=1 energy level, has wavelengths in the ultraviolet region. The Balmer series, corresponding to transitions to the n=2 energy level, has wavelengths in the visible region.
When electrons move to lower levels they lose energy?
When electrons move to lower energy levels within an atom, they release energy in the form of electromagnetic radiation. This energy is emitted as photons in various wavelengths depending on the change in energy levels.
How does the arrangement of electron configuration creates different wavelengths?
It determines the different energy levels. When excited electrons drop back to normal level, energy is released as light photons. Different colors for different frenquencies.
What is the source of an emitted photon?
An emitted photon is typically generated when an electron transitions from a higher energy level to a lower energy level within an atom or molecule. This transition releases energy in the form of a photon.
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.

What causes an atom to release energy in the form of visible wavelengths of light?
When an atom releases energy in the form of visible wavelengths of light, it indicates that an electron in that atom has gone from an excited energy level, back down to a lower energy level.
Why do you see color when you burn a metallic salt?
During the burning process, electrones shift between different energy levels. Returning from a higher to a lower energy level, electromagnetic waves (light) are emitted. Depending on what substance was burned, waves of different length are emitted, i.e. light of different color is radiated.
