Question

Can electrons change orbitalsinside an atom??? when will it release energy?? (when the electron goes from outer orbital to inner or oposite?)

Answer 1

Electrons can move inward or outward, but only to an unoccupied orbital. Movement is accompanied by a specific (fixed) quantity of energy; thus, the atomic spectra of atoms. With high enough energy, all electrons can by stripped. If atoms are aligned properly and energized with the proper energy, lasing (laser) is produced. Burning elements over a flame gives specific colors corresponding to certain electron excitations.

Answer 2

Electrons orbiting the atom have specific energy levels within the atom's structure. They can under certain conditions absorb energy and "jump" up to a higher energy level. The reverse is also possible, should an electron find itself with excess energy it can release it (in the form of a photon or light) and "jump" back down.

The electron will release energy when going from a higher energy level to a lower one, in other words when "jumping" from the outer level to the inner level. If going from an inner level to an outer level it will absorb energy.
