Question

8. What is energy of first Bohr's orbit?​

Answer 1

Answer:

The energy of an electron in the first Bohr orbit is `-13 eV` .

Answer 2

$\huge\red{\underline{{\bf A}}}\huge\orange{\underline{{\bf n}}}\huge\green{\underline{{\bf s}}}\huge\blue{\underline{{\bf w}}}\huge\purple{\underline{{\bf e}}}\huge\pink{\underline{{\bf r}}}$

Excited state is given as = 

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

e.g, n = 2,E =

$\frac{ - 13.6}{4} = \: 3.4ev$
