Question

what is the energy of electron in 4rt orbit of hydrogen​

Answer 1

Answer:

Energy of Electron in 4th Orbit = -0.85 eV

Explanation:

We Have :-

Electron in 4th Orbit

To Find :-

Energy of electron

Formula Used :-

$Energy = \frac{-13.6}{n^{2} } eV$

Solution :-

n = orbit in which electron is present

$Energy = \frac{-13.6}{4^{2} } \\\\= \frac{-13.6}{16}\\ \\= -0.85 eV$
