JEE Mains · Chemistry · STD 11 - 2. structure of atom
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 a \(a_0\))
- A The probability density of finding the electron is maximum at the nucleus
- B The electron can be found at a distance \(2 \mathrm{a}_0\) from the nucleus
- C The 1 s orbital is spherically symmetrical
- D The total energy of the electron is maximum when it is at a distance \(a_0\) from the nucleus
Answer & Solution
Correct Answer
(D) The total energy of the electron is maximum when it is at a distance \(a_0\) from the nucleus
Step-by-step Solution
Detailed explanation
1. \(\Psi^2=\) Probability density is maximum at nucleus. 2. Electron can exist upto infinity from nucleus. 3. True 4. Energy of electron is maximum at infinite distance from nucleus.
