Which type of spectrum is produced by nebulae consisting of atoms that release photons when electrons jump from high-energy states to lower-energy states?
Emission spectrum is produced by nebulae consisting of atoms that release photons when electrons jump from high-energy states to lower-energy states.
What is a spectrum that comes from noncompressed gas called?
The spectrum that comes from a noncompressed gas is called an emission spectrum. It consists of discrete lines of light at specific wavelengths that are emitted when electrons in the gas atoms move to lower energy levels.
What are the colors in the emission spectrum of Sunlight?
The colors in the emission spectrum of sunlight range from violet to red. This spectrum is created by the various wavelengths of light emitted by the sun, and can be seen when sunlight is passed through a prism or diffraction grating, creating a rainbow of colors.
What form of energy emission accompanies the return of an excited electron to its ground state?
What form of energy emission accompanies the return of excited electrons to the ground state?
What is the source of atomic emission spectra?
In an atom of any element there are electrons in the valence shell . Each shell has a fixed no of sub shells that are characterized by specific quantum nos. So this holds true for the valence shell also . Depending on the distance of the valence electrons from the nucleus and its electro static effect on the valence electrons these valence electrons absorb energy from any high energy source that comes in its proximity. Now the entire atom has become a high energy species but by the law of thermodynamics(and nature )every body in the universe tends to have minimum energy and achieve stability. So these high energy electrons tend to emit the absorbed energy and come back to a lower energy state for maximum stability .In the process the emitted energy is observed as spectral lines in a spectrometer .These spetral lines together form what we call as emission spectrum
Image of emission or absorption spectrum of manganese?
This would consist of several series of lines corresponding to the energies of electron transitions. They are bright lines for an emission spectrum and dark for absorbtion.
An emission spectrum of an atom is produced when its electrons are .?
Releasing Energy
Is it possible for two metals to have the same emission spectrum?
No. It is not possible for two metals to have the same emission spectrum. For metals to have the same emission spectrum, they would need for their electrons to have duplicate orbitals. That would be impossible due to the exclusion principle.
What is the the spectrum emitted by discharge tube?
The spectrum emitted by a discharge tube typically consists of discrete lines corresponding to the characteristic emission wavelengths of the elements or gases inside the tube. This emission spectrum results from the de-excitation of electrons in the atoms or molecules within the tube when they return to lower energy levels, emitting photons of specific energies. This emission pattern is unique to each element or gas, enabling scientists to identify the substances present in the discharge tube.
Why would the absorption spectrum of each element have lines in the same places as in its emission spectrum?
The absorption spectrum of an element have lines in the same places as in its emission spectrum because each line in the emission spectrum corresponds to a specific transition of electrons between energy levels. When light is absorbed by the element, electrons move from lower energy levels to higher ones, creating the same lines in the absorption spectrum as the emission spectrum. The frequencies of light absorbed and emitted are the same for a specific element, resulting in matching lines.
Is an atomic emission spectrum a continuous range of colors?
No, an atomic emission spectrum is not a continuous range of colors. It consists of discrete lines of specific wavelengths corresponding to the emission of light from excited atoms when they return to lower energy levels. Each element has a unique atomic emission spectrum due to its unique arrangement of electrons.
How is the light of an emission spectrum of an element produced?
Basically, energy is emitted when an electron falls from a higher energy level to a lower energy level. Such energy is emitted as electromagnetic waves, which in certain cases can be visible light.
Explain the difference between the continuous spectrum of white light and the atomic emission spectrum of an element?
The difference between continuous spectrum and the atomic emission espectrum of an element is that in emission spectrum, only certain specific frequencies of light are emitted while in a continuous spectrum, a continuous range of colors are seen in the visible light.
How does the number of lines in the emission spectrum for an element compare with the number of lines in the absorption spectrum?
The number of lines in the emission spectrum is the same as in the absorption spectrum for a given element. The difference lies in the intensity of these lines; in emission, they represent light being emitted, while in absorption, they represent light being absorbed.
What is the total collection of photons emitted by a given atom?
The total collection of photons emitted by a given atom is known as its emission spectrum. This spectrum consists of photons with specific energies corresponding to transitions between different energy levels of the atom. The emission spectrum is unique to each element and can be used to identify elements based on the pattern of emitted photons.
What is the name of the range of colors emitted by a heated atom?
The name of the range of colors emitted by a heated (energized, excited, etc...) atom is called an emission spectrum.
Explain the production of an emission spectrum in terms of energy states of an electron?
When an electron in an atom jumps from a higher energy state to a lower one, it releases energy in the form of photons. Each electron transition corresponds to a specific energy difference, resulting in the emission of photons with distinct energies. This emission spectrum displays sharp peaks at wavelengths corresponding to these energy differences.
