What does the change of an atom from an excited state to the ground state always require?
An atom emits a photon (particle of light) when transitioning from a ground state to its excited state. To obey conservation of energy, the energy gained by the atom when an electron moves to a lower energy level is equal to the energy it loses in emitting the photon. (The energy of a photon is E = hf, where E is the energy, h is Planck's constant, and f is the frequency of the photon.) Conversely, when an atom absorbs a photon (as is the case in absorption spectra), the electron absorbing the photon moves to a higher energy level.
What is padmanabha rao effect in radioisotopes and xrf sources?
M.A.Padmanabha Rao's Discovery 6: NEW ATOMIC PHENOMENON (PADMANABHA RAO EFFECT)The previously unknown atomic phenomenon reportedly taking place in radioisotopes and XRF sources explains how gamma, beta or X-ray emission successively generates Bharat radiation (first generation), which in turn the UV dominant optical emission (second generation) within the same excited atom. This phenomenon is known as Padmanabha Rao Effect.The phenomenon takes place in two stages.(1) Ionizing radiation energy, particularly gamma, beta or X-ray energy at keV or MeV level loses energy just at eV level while passing through a core-Coulomb field. The loss of energy is reproduced as electromagnetic radiation (Bharat radiation) with the same energy at eV level but higher than that of UV or EUV that the source emits.(2) In turn, the Bharat energy generates UV dominant atomic spectrum on valence excitation.Padmanabha Rao Effect taking place in radioisotopes and XRF sources is reported to be causing Sunlight from Sun.
The lines in the bright line spectrum of an atom are due to what?
The atomic line spectrum comes from the emission of atoms of different elements that are in an excited state. Each element has its own unique atomic emission spectrum.
Types of radioactive emission?
The nuclei of radioactive elements may emitt one or more of the following; Gamma Rays --- very energetic electromagnetic wave pulses Beta Negative Rays --- electrons Beta Positive Rays ---- positrons (positive electrons) Alpha Rays ------ a composite particle consisting of 2 neutrons & 2 protons.
Why is a ladder not a good model for the atom?
a ladder could be used to interpret the emission of light when an electron gets excited, moves to a higher rung, and then falls to a lower or bottom rung. otherwise, it shows nothing of how the atom is constructed, the number of protons, neutrons, electrons, etc
Is the emission of electromagnetic radiation by an excited atom is it a wave or a particle?
a particle traveling in wave form.
What theory of light best explains the emission of electromagnetic radiation of an excited atom?
Quantum Mechanics
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.
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 does the change of an atom from an excited state to the ground state always require?

How is a gamma particle formed?
A gamma particle, which is a photon of high-energy electromagnetic radiation, is typically formed during nuclear reactions such as beta decay or fusion. When a nucleus transitions from an excited state to a lower-energy state, it emits a gamma particle to balance its energy levels.
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
How is the atomic number changed by gamma decay?
There is no change in atomic number with the emission of gamma radiation. Unlike alpha or beta radiation, it does not have any kind of particles. It's emission results only when an excited nuclei goes to an unexcited state by emitting these.
What type of radiation is cobalt 60?
Cobalt-60 decays by beta particle emission to highly excited isomers of Nickel-60, as these isomers relax to the ground state of Nickel-60 highly energetic gamma rays are emitted.
Characteristic series of frequencies of electromagnetic radiation substances emit?
Each substance emits a unique characteristic series of frequencies of electromagnetic radiation when it is heated or excited. These frequencies correspond to specific energy transitions within the atoms or molecules of the substance. By studying these emission spectra, scientists can identify the composition of the substance and gain insights into its structure and properties.
When an atom in an excited state returns to it's ground state what happens to the energy?
When an atom in an excited state returns to its ground state, it releases energy in the form of electromagnetic radiation, typically as light or photons. The energy released corresponds to the difference in energy between the excited state and the ground state. This phenomenon is fundamental to processes such as fluorescence and the emission spectra of elements.
When an atom in the excited state returns to its ground state what happens to the excess energy of the atom?
When an atom in an excited state returns to its ground state, it releases the excess energy in the form of electromagnetic radiation, typically as a photon. The energy of the emitted photon corresponds to the difference in energy levels between the excited state and the ground state. This process is fundamental to phenomena such as fluorescence and the emission spectra of elements.
