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 a₀ )

Options

  1. AThe probability density of finding the electron is maximum at the nucleus
  2. BThe electron can be found at a distance 2 a ₀ from the nucleus
  3. CThe 1 s orbital is spherically symmetrical
  4. DThe total energy of the electron is maximum when it is at a distance a₀ from the nucleus

Correct answer

D. The total energy of the electron is maximum when it is at a distance a₀ from the nucleus

Step-by-step solution

1. ^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.
