Which one of the following about an electron occupying the 1s orbital in a hydrogen atom is incorrect? (The Bohr radius is represented by a0{a}_{0} ).Which one of the following about an electron occupying the 1s orbital in a hydrogen atom is incorrect? (The Bohr radiusWhich one of the following about an electron occupying the 1s orbital in a hydrogen atom is incorrect? (The Bohr radius

Options

  1. AThe total energy of the electron is maximum when it is at a distance a0{a}_{0} from the nucleus.
  2. BThe electron can be found at a distance 2a02{a}_{0} from the nucleus.
  3. CThe probability density of finding the electron is maximum at the nucleus.
  4. DThe magnitude of the potential energy is double that of its kinetic energy on an average.

Correct answer

B. The electron can be found at a distance 2a02{a}_{0} from the nucleus.

Step-by-step solution

Which one of the following about an electron occupying the 1s orbital in a hydrogen atom is incorrect? (The Bohr radius
Which one of the following about an electron occupying the 1s orbital in a hydrogen atom is incorrect? (The Bohr radius
From the graph it is clear that probability of finding electron is maximum at the nucleus
