What are Electrons and Excitation?

electrons move around a nucleus of an

atom in concentric orbits these orbits

or shells represent different energy

states that electrons can exhibit

the farther and electron is from the

nucleus the greater its potential energy

while electrons typically remain in

their prescribed orbital energy level

it's possible for an electron to be

knocked from its lower orbit into a

higher one

thus a bombarding free electron can

collide with the bound electron raising

it to a higher orbit or energy level

this electron is now in a state of


however this higher orbital status is

fleeting the electron will be quickly

drawn back toward the nucleus and

returned to its original orbit during

this transition back to its normal state
