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? (The Bohr radius is represented by \(a_0\)
- A The electron can be found at a distance \(2a_0\) from the nucleus
- B The probability density of finding the electron is maximum at the nucleus
- C The magnitude of potential energy is double that of its kinetic energy on an average
- 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
\(T.E = - K.E = \frac{{PE}}{2}\) The energy of electrons increases as they are away from the nucleus. The probability of finding the \(1s\) electron may be higher at \(a_0\) but the energy is not. The probability density of finding the electron is not zero at any place in the…
