Excited mercury atoms emit light strongly at a wave of 436 nm What is the frequency of radiation What is the energy of this radiation Good illustration of the electromagnetic spectrum?
Ultraviolet. Most of the spectrum is invisible to people.
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.
Why different materials have different colors?
Because every material has unique allowed energy levels, the electromagnetic radiation emitted from them, which is equal to the energy of the higher excited state minus the energy of the lower excited state (or ground state) are also going to be unique. Since color is based on an electromagnetic wave's frequency, which in turn is proportional to energy, these unique waves give unique colors.
What is the emission of electromagnetic radiation by an excited atom called?
Gamma radiation is high-energy photons emitted by a radioisotope.
When U-238 decays to th-234 what has been emitted?
When U-238 decays to Th-234, an alpha particle is emitted. An alpha particle consists of two protons and two neutrons, and is essentially a helium nucleus.
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.
The specific pattern of colors emitted by excited atoms is called a?
'Spectrum'.
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.
Whenever an excited hydrogen atom falls back from an excited state to its ground state it?
The answer is (B) Emits a Photon of Radiation.
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 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.
Why is mercury used in streetlights?
The light emitted by excited mercury gas is predominantly in the visible spectrum and as a light source is relatively efficient.
Excited mercury atoms emit light strongly at a wave of 436 nm What is the frequency of radiation What is the energy of this radiation Good illustration of the electromagnetic spectrum?
Ultraviolet. Most of the spectrum is invisible to people.
What is fluorescence in diamonds?
From Secret Diamond: "Diamond fluorescence is the visible wavelengths emitted by diamond when excited by invisible radiation." You can read more about it, below.
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 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
Why different materials have different colors?
Because every material has unique allowed energy levels, the electromagnetic radiation emitted from them, which is equal to the energy of the higher excited state minus the energy of the lower excited state (or ground state) are also going to be unique. Since color is based on an electromagnetic wave's frequency, which in turn is proportional to energy, these unique waves give unique colors.
