JEE Main 2025 Chemistry question

Which one of the following about an electron occupying the 1s orbital in a hydrogen atom is incorrect ? (Bohr's radius is represented by a0)

(1)The probability density of finding the electron is maximum at the nucleus
(2)The 1s orbital is spherically symmetrical
(3)The total energy of the electron is maximum when it is at a distance a0 from the nucleusCorrect
(4)The electron can be found at a distance 2a0 from the nucleus

Answer: (3)

Solution

Energy increases (becomes less negative) as n increases (farther from nucleus), not maximum at a0
