Which one of the following about an electron occupying the 1 s orbital in a hydrogen atom is incorrect?
(Bohr's radius is represented by $\mathrm{a}_0$)
The probability density of finding the electron is maximum at the nucleus
The total energy of the electron is maximum when it is at a distance $a_0$ from the nucleus
The electron can be found at a distance $2 a_0$ from the nucleus
