The wave function of an electron in the lowest energy state of a hydrogen atom is proportional to

e^{-r / a_0}

, where

r

is the distance of the electron from the nucleus. Probability is maximum when electron is at

View answer and explanation

Correct option: A

the nucleus

Option A (the nucleus) is correct because the probability density is proportional to the square of the wave function, which is maximum at the nucleus (r=0).
