WebHence the energy is negative in comparison to an unbound electron. Now in the just above formula if you imagine an electron to be a positively charged particle then you would get a positive potential energy which actually means that the electron will be repelled until it retches infinite separation. Web3 Answers Sorted by: 17 We say that a free, unbound electron has zero energy (that's convention, you could just as well put another number there). This means that the level n = ∞ is fixed at E ∞ = 0 eV. WebAnswer (1 of 9): A completely free electron is one that is not bound to an atom or crystal as the other answers have said.
