In a practical, simplified sense it is the orbital "shell" that an electron can occupy (quantum theory contends that electrons cannot occupy just any old space around a nucleus, but is restricted to specific "levels", "volumes" or "shells"). More general information is in the article in the link below.

∙ 11y agoAll atom has two parts which make up their structure. These are the nucleus and the energy levels(Shells). The subatomic particles proton and neutron are found inside the nucleus while electrons are found on the energy levels. So energy levels mean a lot for the structure of an atom.

∙ 13y agoIt means that there are certain discrete energy levels that an atom can attain, by promoting electrons to higher-energy orbitals. The energy state of an atom is not continuously variable: each possible orbital to which an electron can be promoted has a certain energy level. As an electron "drops" from a high-energy orbital to a lower-energy one, a discrete amount of energy is released in the form of a photon. Whether this is visible light, IR, UV, gamma or X ray depends on the photon's energy (and therefore its wavelength).

What do you call an atom if you move an electron in an atom from a low energy level to a higher energy level within the atom?
no , it only emits energy if it moves from a higher energy level to a lower energy level.
When an atom has one or more electrons in higher energy levels?
An atom has multiple energy levels. When an atom has more electrons than it can fit into an energy level, then it puts them into the next higher energy level.
What is the energy level of an atom occupied by?
Electrons
Region of atom in which electrons of the same energy are found?
An energy level
What is the maximun number of electrons in the second energy level of an atom?
The maximum number of electrons in the second energy level of an atom is 8.
What do you call an atom if you move an electron in an atom from a low energy level to a higher energy level within the atom?
no , it only emits energy if it moves from a higher energy level to a lower energy level.
What is the energy state of an atom?
The energy state of an atom is an energy level.
What happen when an atom has more electrons that can fit in one energy level?
An atom has multiple energy levels. When an atom has more electrons than it can fit into an energy level, then it puts them into the next higher energy level.
What is meant when a atom is In ground state?
It is the lowest allowed energy state of an atom, molecule, or ion.
How many electrons are the third energy level of a calcium atom?
There are 8 electrons in the third energy level of a calcium atom.
How many electrons are in the second energy level of a boron atom?
A boron atom has three electrons in its second energy level.
What is the energy level of an atom?
Depends upon the atom and element, some have an energy level of 0 and it can be +/- for others depending on the number of protons or electrons in said atom.
When an atom has one or more electrons in higher energy levels?
An atom has multiple energy levels. When an atom has more electrons than it can fit into an energy level, then it puts them into the next higher energy level.
How many electrons of a neutral atom of magnesium are in its outermost energy level?
A neutral atom of magnesiumhas two electronsin its outermost energy level
How many electrons can an atom's third energy level hold?
The third energy level of an atom can hold eight electrons.
What is the energy level of an atom occupied by?
Electrons
What causes an atom to release energy in the form of visible wavelengths of light?
When an atom releases energy in the form of visible wavelengths of light, it indicates that an electron in that atom has gone from an excited energy level, back down to a lower energy level.
