When an electron returns to its ground state it emits energy in the form of light.
line emission
It immediately falls back to the ground state and emits a photon of light.
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 moves to a lower energy level, the difference in energy appears in the form of a photon, which the electron emits.
Just the opposite. As an electron returns to a lower energy level, it emits a packet (quantum) of energy that may be a visible photon.

it emits different colours. Hope it helps.

it becomes stable.
when an electron moves from excited state to ground state it emits photons of wavelength equal to the difference between the two energy levels. Consider a hydrogen atom. If the electron is at the second energy level in the atom (the energy of this level is -3.4 eV )it can stay there for about only 10^-8 s and then after that it just to the level below .If it jumps from second to ground state (energy of ground state is -13.6 eV) it emits aphoton of energy = 13.6-3.4 =10.2 eV. .............................Gho$t

Just the opposite. As an electron returns to a lower energy level, it emits a packet (quantum) of energy that may be a visible photon.
The capture creates a "hole", or missing electron, that is filled by a higher energy electron that emits X-rays.
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.
