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 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.


What was The quantum theory of energy levels within atoms was aided by?

The quantum theory of energy levels within atoms was aided by the emission spectrum. When excited with light, different elements emitted photons of different frequencies. The frequencies were different because the energy difference from excited to low energy state was different depending on the element.


What is the release of energy by particles of matter that have absorbed extra energy called?

Radiation. Different levels of energy dictate the type of radiation that is emitted. Extremely excited particles might emit visible light or even x-rays while particles that are not very excited might emit weak radio waves. This range from weak radiation to strong radiation is called the electromagnetic spectrum.


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.


What are the characteristics of the nitrogen emission spectrum?

The nitrogen emission spectrum is characterized by a series of distinct lines of light that are emitted when nitrogen atoms are excited. These lines are specific to the energy levels of nitrogen atoms and can be used to identify the presence of nitrogen in a sample.


What does the term bright line spectrum mean?

A bright line spectrum refers to the pattern of distinct and bright lines of different colors that are produced when an element is excited and emits light. Each element has a unique bright line spectrum that can be used to identify the element through spectroscopy.


What you observe if light from argon gas were passed through a prism?

If light from argon gas were passed through a prism, you would observe it splitting into its different wavelengths or colors, creating a spectrum. The spectrum produced would consist of a few distinct lines corresponding to the specific wavelengths of light emitted by the excited argon atoms. This pattern of lines is known as an emission spectrum and can be used to identify the presence of argon gas.


What kind of spectrum does a hot low density gas give rise to?

A hot low density gas gives rise to an emission spectrum. This is because the electrons in the gas become excited and move to higher energy levels when the gas is heated, and then emit radiation as they return to lower energy levels. This emitted radiation forms distinct spectral lines that are characteristic of the elements present in the gas.


What types of electromagnetic radiation can be released when an electron falls from an excited state to a ground state?

Whenever the electron falls from an excited state to a lower level, energy is released in the form of electromagnetic radiation. The Electromagnetic radiation can be light of different wavelengths and therefore different colors


What is the emission of electromagnetic radiation by an excited atom called?

The emission of electromagnetic radiation by an excited atom is called spontaneous emission. This process occurs when an atom transitions from a higher energy state to a lower energy state, releasing a photon in the form of electromagnetic radiation in the process.
