Question

Calculate the angular momentum of the electron in the third Bohr orbit of hydrogen atom.

Data: e = 1.6 × 10^-19 C, 

m_e = 9.1 × 10^-31 kg, 

h = 6.63 × 10^-34 J∙s, 

c = 3 × 10⁸ m/s. I eV = 1.6 × 10^-19 J, 

ε₀ = 8.85 × 10^-12 F/m, 

R = 1.097 × 10 m 1, 

1/4πε₀ = 9 × 10⁹ N∙m² /C²

Answer 1

Data: n = 3 

The angular momentum, L = \(\cfrac{nh}{2\pi}\)
