Question

If the electron jumps from 7.0 eV energy level to
| 5.0eV energy level, it:
(a) Absorbs 2.0 eV kinetic energy
(b) Absorbs 2.0 eV potential energy
(c) Emits 2.0 eV electrical energy
(d) Emits 2.0 eV photon​

Answer 1

Answer:

emit 2.0ev photon. because 7.0- 5.0 (work function) = 2.0

Answer 2

Explanation:

If the electron jumps from 7.0 eV energy level to

| 5.0eV energy level, it:

(a) Absorbs 2.0 eV kinetic energy

(b) Absorbs 2.0 eV potential energy

(c) Emits 2.0 eV electrical energy

(d) Emits 2.0 eV photon
