Question

Calculate the energy of the electron in the ground state of the hydrogen atom. Express it in joule and in eV. 

[m_electron = 9.11 × 10^-31 kg, e = 1.6 × 10^-19 C, h = 6.63 × 10^-34 J∙s, ε₀ = 8.85 × 10^-12 C² /N∙m² ]

Answer 1

Data : m = 9.11 × 10^-31 kg, 

e = 1.6 × 10^-19 C, 

h = 6.63 × 10^-34 J∙s, 

ε₀ = 8.85 × 10^-12 C² /N∙m²

The energy of electron in nth Bohr orbit is

For the ground state, n = 1.
