Energy lost by an electron during its transition from an outer to an inner orbit is emitted as a flash of light called an emission. Light/energy emissions are released in a characteristic manner (wavelength) that corresponds to the amount of energy lost.
proton
Electromagnetic radiation
A packet of light energy is called a photon.
This phenomenon is called phosphorescence.
the gamma ray.
its called an isotope c:
In a transition to ground state, a photon is radiated away. It carries off the energy to make a transition to ground state possible. As soon as it is created, the photon is off to the races. It travels away at the speed of light (for the medium in which it is moving).
Radiation
The energy is called electromagnetic radiation (light energy).
The detection of physical energy emitted or reflected by physical objects is called remote sensing. This technology is used to gather information from a distance by recording and analyzing the energy that is emitted or reflected by objects on the Earth's surface.
This electron is called excited.
If an electron is released from the nucleus (and not from an electron shell) then it would have been emitted by a neutron in beta decay. In beta-minus decay, a neutral neutron emits an electron and an anti-neutrino and becomes a proton; in beta-plus decay, a proton emits a positron and a neutrino and becomes a neutron.
