Energy Levels
Many people helped in interpreting that message, and the story told here is a great oversimplification. The foundation was Einstein's formula, discovered in 1905

Neils Bohr numbered the energy levels (n) of , with level 1 (n=1) being the ground state, level 2 being the first excited state, and so on. Remember that there is a maximum energy that each can have and still be part of its atom.
ENERGY LEVEL - Essentially synonymous with electron shell.
ENERGY STATE - Complete set of variable values that a particle can exhibit.
Energy Level
One of a number of states an electron may occupy in an atom, depending on its binding energy.

Energy Level - Any of the many energy states that an atom may have. Different energy levels correspond to different distances of the electron from the nucleus ...
Energy Level
(a) Any of the several discrete states of energy in which an atom or ion can exist. For example, an orbital electron can exist only in those energy levels that correspond to an integral number of deBroglie wavelengths in a Bohr atom.
Energy level
A Quantum mechanics system or particle that is Bound state, confined spatially, can only take on certain discrete values of energy, as opposed to Classical mechanics particles, which can have any energy....

The energy levels of hydrogen can be calculated fairly accurately using the Bohr model of the atom, which conceptualizes the electron as "orbiting" the proton in analogy to the Earth's orbit of the sun.
Plot of energy level against wavelength for heat or other radiation emitted by an object capable of absorbing all the energy that strikes it. The curve has a pronounced hump that moves toward shorter wavelengths as the temperature increases.
Hydrogen Energy Levels is a simple applet demonstrating the use of the Bohr equation to calculate the energy levels of a hydrogen atom. It shows an energy level diagram vertically from infinity to the ground state.

energy level (NASA Thesaurus / NASA SP-7, 1965) Any one of different values of energy which a particle, atom, or molecule may adopt under conditions where the possible values are restricted by quantizing conditions.
The energy of the electron produced is equal to the energy of the incident photon minus the amount of work needed to raise the electron to a sufficient energy level to free it from the surface.
An ion spectrometer consisting of a hemispherical electrostatic energy analyzer with a quadrupole electrostatic lens at the aperture was pointed towards the sun, to measure solar wind ions at 30 energy levels logarithmically spaced between 50 eV and ...
These bands correspond to the allowed energy levels in the atoms. A similar phenomenon occurs for emission. As the electrons descend to lower energy levels, a spectrum is emitted that represents the jumps between the energy levels of the electrons.
electron negatively-charged subatomic particle that moves around the atomic nucleus in specific energy levels. It has about 1800 times less mass than the proton and neutron.
The atom has a structure that allows for orbits up to only a certain energy level - sort of like the top of the mountain. If the electron absorbs too much energy and then goes up, there is no level that it can land in, since it has too much energy.
The first one is your energy level. Suppose you have had a tough week at work, that you have had little sleep all week, it is 2 a.m. on a Saturday morning and that you're trying to spot a very faint object.
electromagnetic spectroscopy - The study electomagnetic radiation spectra given off or absorbed by atoms or molecules changing energy levels.
Atomic absorption spectroscopy ...
The presence of spectral lines is explained by quantum mechanics in terms of the energy levels of atoms, ions and molecules.
Atoms and molecules exist at low and high energy levels. Those at low levels can be excited to higher levels, usually by heat, and after reaching the higher levels they give off light when they return to a lower level.
First, the 26 electrons of a normal iron atom can make an enormous number of different transitions among energy levels. Second, many iron atoms are ionized, with some of their 26 electrons stripped away.
The triple alpha process is highly dependent on carbon-12 having a resonance with the same energy as helium-4 and beryllium-8 and before 1952 no such energy level was known.
For densities, we want pairs of lines from energy levels with nearly the same excitation energy but quite different A-values; now the thermal populations will be the same to within the statistical weights, ...
For example, molecules, which consist of atoms bound together (such as water which is two hydrogens bound to an oxygen) have energy levels which can emit and absorb specific wavelengths of light.
When an atom or molecule is excited by some process, one or more electrons within it can be raised to higher "orbits" or energy levels.
The intensity of the lines is determined by both the abundance of the particular element and its state of ionization, as well as by the excitation of the atomic energy level involved in the line.
As the energy level of radiation is increased, the wavelength becomes shorter and shorter. When the human eye perceives different wavelengths of visible light, we interpret it as different colors.
Every chemical element has absorption lines at several particular wavelengths corresponding to the differences between the energy levels of its atomic orbitals.
Then the electrons drop to a lower energy level, emitting a photon of the same frequency and traveling in the same direction as the incident, stimulating photon.
According to the simple Bohr model, an atom consists of a nucleus around which electrons buzz in orbits. Each electron orbit represents a discrete energy level; the lowest energy levels are those closest to the nucleus.
It emits characteristic wavelengths of light known as Lyman-alpha radiation. This radiation is emitted from the cloud when the electrons in hydrogen atoms drop from energy level two to energy level one within the atom's orbital shells.
The scientific instruments on-board the satellite include a high-resolution camera that records the X-ray images and a spectrometer that determines the energy level of the X-rays.
In the atom the dominant force is the electrical force between the nucleus and the electrons; this force determines the characteristic structure, or energy levels, of the atom.
As the CME matter spreads out rapidly from the Sun, it drives a shock-wave that excites the quiet particles it hits to high energy levels.
When a shock-wave passes Earth, our planet's magnetosphere is disturbed causing a geomagnetic storm.
model rests on three ideas: that there is a state of lowest energy, that there is a maximum energy, beyond which the electron is no longer bound to the nucleus, and that within these two energies the electron can only exist in certain energy levels.
by some types of atom, ion, or molecule. Any atom, ion or molecule has its own set of characteristic absorption lines which appear when electrons associated with the atom, ion, or molecule absorb radiation and jump to higher energy levels.
Photons, seen as particle carriers of the electromagnetic force, are described in terms of energy level using the electron Volt (eV). Throughout this document the preferred treatment will be waves, which is arguably a more informative approach.
This argument cannot be true because the collective light from the faint stars, if these stars be infinite in number, must render the night sky brilliant. It is akin to the fact that we cannot observe one electron dropping to a lower energy level in ...
