Want this question answered?
A photon is emitted when an electron falls from a higher to lower orbital. A photon is an elementary particles, the quantum of light and all other forms of electromagnetic radiation.
Drops to a lower energy level and emits one photon of light.
Only one photon is produced per electron in any de-excitation. The number of energy levels it drops only determines the energy of the photon emitted.
In beta- decay, an electron and an electron antineutrino is emitted. In beta+ decay, a positron and an electron neutrino is emitted. In both types of decay, if the nucleus is left in an excited state, when it comes back down to ground state, it emits a photon in the form of a gamma ray. In beta+ decay that is precipitated by K Capture, the electron cloud is left in a multi level excited state, and it has one or (usually) more drops in energy as it returns to ground state, each drop emitting a photon in the form of an x-ray.
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.
The energy of the photon is the same as the energy lost by the electron
The energy of the photon is the same as the energy lost by the electron
A photon is emitted when an electron falls from a higher to lower orbital. A photon is an elementary particles, the quantum of light and all other forms of electromagnetic radiation.
When light (a photon) collides with an atom, the energy contained by it is absorbed and it bumps one of the electrons orbiting it up to a higher energy level. ( there are several energy levels, think of it as stories of a building) Later when the electron falls down 1 or more energy levels, The energy is released as another photon. If the electron drops down to the original energy level, the same intensity photon is released as was absorbed. If it drops down in 2 or more steps, several photons will be released of varying intensity, depending on the amount of levels dropped.
You may be confusing "proton" with "photon". A proton is a positively-charged particle contained within the nucleus of an atom. A photon is a discrete unit of energy normally expressed as light. Around the nucleus of the atom, there are some electrons in energy levels. When an atom absorbs energy, it absorbs a specific amount, or "quantum" of energy and the electron boosted to a higher energy level. When the electron drops to a lower energy level, it emits a photon in the form of light at a specific energy and frequency.
Drops to a lower energy level and emits one photon of light.
Only one photon is produced per electron in any de-excitation. The number of energy levels it drops only determines the energy of the photon emitted.

No, the energy released by electron might be taken by enviornment. Electron remains in the infuence of corresponding nuclei, in another energy level.
An excited electron spontaneously drops back to its ground state, emitting a photon of light as it does so. <><><><><> The same thing happens in the nucleus. An excited nucleus drops down to a lower energy level, releasing a photon.
An electron has dropped from a higher energy state to a lower one. The photon emitted has precisely the same energy as was lost by the electron.
It gains energy in a quantized amount
