When an electron is moved to a higher energy level,
after absorption, the quantum no longer exists as a separate entity -- its energy has been seamlessly integrated ...into the orbital energy of the electron. If the electon absorbs another quantum, that is likewise integrated seamlessly. if the electron drops down a level toward the nucleus, it emits some of its energy as a quantum, outside the electron, that quantum exists as a photon (electromagnetic radiation). inside an electron, there are no separate or independent quanta. in case of an annihilation, ALL the energy of the electron turns into one quantum (and all the energy of the positron into another quantum).
If i didn't do a good job of explaining this, please post in the DiscBrd AND send me a private message, and i will try to clarify.
You can assume that it absorbed or received energy from somewhere.
The electorn has gained energy.
In the Bohr model of the atom, an electron emits a photon when it moves from a higher energy level to a lower energy level.
no , it only emits energy if it moves from a higher energy level to a lower energy level.
"Absorbed"
it loses energy
excitation
Electron X absorbs energy when it changes to a higher energy level. Electron X absorbs energy when it changes to a higher energy level. It takes energy to do that.
the electron will gain energy
The electron gains energy.
In the Bohr model of the atom, an electron emits a photon when it moves from a higher energy level to a lower energy level.
The electron gains energy.
excited
no , it only emits energy if it moves from a higher energy level to a lower energy level.
No, the energy released by electron might be taken by enviornment. Electron remains in the infuence of corresponding nuclei, in another energy level.
This electron is called excited.
"Absorbed"
it loses energy
Electrons are normally in an energy level called the ground state. In the ground state electrons absorb heat energy and then get into the excited state where they release the energy and exert light energy. The light energy can be seen with a spectroscope with a unique bright line emission spectrum.
