Chemistry · Bohr model of a hydrogen atom: its postulates, derivation of the relations for the energy of the electron and radii of the different orbits, limitations of Bohr's model
The radius of the stationary state which is also called Bohr radius is given by
The radius of the stationary state which is also called Bohr radius is given by the expression \( r_{n}=n^{2} a_{0} \) where the value of \( a_{0} \) is:
- A. 52.9 pm
- B. 5.29 pm
- C. \( 529 \mathrm{pm} \)
- D. 0.529 pm
Step-by-step solution
The Bohr radius (a₀) is a physical constant equal to approximately 0.529 Å. Since 1 Å = 100 pm, 0.529 Å = 52.9 pm. Therefore, option A is correct.
