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 $a_0$)
  1. The probability density of finding the electron is maximum at the nucleus
  2. The electron can be found at a distance $2 \mathrm{a}_0$ from the nucleus
  3. The 1 s orbital is spherically symmetrical
  4. The total energy of the electron is maximum when it is at a distance $a_0$ from the nucleus

Solution


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.
