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 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?
Gamma radiation is high-energy photons emitted by a radioisotope.
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 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.
What happens to molecules if they receive electromagnetic radiation?
They are excited and their energy increases and possibly ejects an electron and change their size and shape..They will often absorb part of the radiation; in that case, their energy will increase.
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 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.
What Kind of energy associated with gamma emission?
Gamma radiation is the emission of an photon from the nucleus with energy relative to the energy step that the nucleus takes in coming down from an excited state down to either an intermediate state or to the ground state.
