Question

An electron is in an excited state in a hydrogen like atom it has total energy of-3.4 ev

Answer 1

Answer:

(-3.4)=+3.4 ( remember, kinetic energy is never negative.) The potential energy is double of total enegy so, it is -6.8. Only if electron is associated with the atom, then this concept is applied, if the electron is free, then total energy will be positive and will be in the form of kinetic energy only.
