Question

Write down the energy of an electron of nth stable shell of hydrogen atom.​

Answer 1

By keeping the electrons in circular, quantized orbits around the positively-charged nucleus, Bohr was able to calculate the energy of an electron in the nth energy level of hydrogen: E ( n ) = − 1 n 2 ⋅ 13.6 eV E(n)=-\dfrac{1}{n^2} \cdot 13.6\,\text{eV} E(n)=−n21⋅13. ... 6eVminus, 13, point, 6, start text, e, V, end text.

Answer 2

$\huge\underline{\underline{\mathfrak \red{Answer}}}$

The formula defining the energy levels of a Hydrogen atom are given by the equation: E = -E0/n2, where E0 = 13.6 eV (1 eV = 1.602×10-19 Joules) and n = 1,2,3… and so on. The energy is expressed as a negative number because it takes that much energy to unbind (ionize) the electron from the nucleus.
