According to Bohr's model, the energy of n = 4 electron in a hydrogen atom is 1.3625 × 10⁻¹⁹J

<h3>Bohr's Model of Hydrogen Atom</h3>

According to the postulates given by Bohr, electrons revolve around the nucleus in fixed circular orbits which are called stationary orbits or stationary states.

The energy of electrons in a stationary state is fixed and given by,

E_n = \frac{-2\pi^2me^4}{n^2h^2} Z^2

where, m = mass of electrons = 9.1 x 10⁻³¹ kg

e = charge on electron = 1.602 × 10⁻¹⁹ C

n = no of orbits

h = Planck's constant

Z= atomic number of H-like particles

After calculating all the constants values, we get

E_n= \frac{-2.18 \times 10^-^{18}}{n^2} \times Z^2\\\\E_n= \frac{-2.18 \times 10^-^{18}}{4} \times 1^2

= 0.13625 × 10⁻¹⁸

= 0.13625 × 10⁻¹⁹ J

Hence, the energy of n = 4 electron in a hydrogen atom is 1.3625 × 10⁻¹⁹J
