MHT CET Chemistry question

The energy of the electron in a hydrogen atom has a negative sign for hydrogen atom because

(A)the energy of the electron in the atom is lower than the energy of a free electron at rest
(B)a free electron at rest is an electron that is infinitely far away from the nucleus
(C)the energy value assigned to free electron at rest is zero
(D)All of the aboveCorrect

Answer: (D)

Solution

The energy of a free electron at rest (infinitely far from the nucleus) is taken as zero, and since an electron bound in the atom is more
