Transition means switching from one energy level to another; the lost energy turns into photons.
neon
The four main types of microscopes are the Light Microscope, Electron Microscope, the Transition electron microscope and Scanning electron microscope.
It can and when it does the electrons do transition into a higher energy orbit.
When an electron moves from an outer to an inner orbit, energy is released in the form of light of a particular wavelength.
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
The n4-n2 transition of hydrogen is in the cyan, with wavelength of 486.1 nm. blue = als
Drops to a lower energy level and emits one photon of light.

Manganese. Transition metal ions exhibit electron transitions between their electron orbitals which absorb light of certain wavelengths, making the compound coloured.
