JEE PYQ: Atomic Structure Question 32
Question 32 - 2019 (09 Apr Shift 2)
Which one of the following about an electron occupying the 1s orbital in a hydrogen atom is incorrect?
(1). (The probability density of finding the electron is maximum at the nucleus.)
(2). (The electron can be found at a distance $2a_0$ from the nucleus.)
(3). (The magnitude of the potential energy is double that of kinetic energy on average.)
(4). (The total energy of the electron is maximum when it is at a distance $a_0$ from the nucleus.)
Show Answer
Answer: (4)
Solution
The total energy of the electron is minimum (not maximum) at distance $a_0$ from the nucleus for 1s orbital.
