The energy associated with the first orbit in the hydrogen atom is –2.18 * 10^–18 J atom^–1 . What is the energy associated with the fifth orbit? Calculate the radius of Bohr’s fifth orbit for hydrogen atom.

Answer & Explanation

E_{5} = \frac{- (2.18 \times 10^{- 18})}{(5)^{2}} = \frac{- 2.18 \times 10^{- 18}}{25} E_{5} = - 8.72 \times 10^{- 20} J

Radius of Bohr’s nth orbit for hydrogen atom r_n=(0.0529nm)n^2
For, n = 5, r_5=(0.0529nm) (5)^2
r_5=1.3225nm
