Question

What is the energy and bohr's radius for the third orbit of hydrogen atom

Answer 1

hydrogen have only one shell so the question is wrong . hydrogen valency also 1 .

Answer 2

$e = - 13.6 \frac{ {z}^{2} }{ {n}^{2} } \\ e = - 13.6 \times \frac{1}{ {3}^{2} } \\ e = - \frac{13.6}{9} \\ \% \\ \bold{\huge{\pink{e = - 1.5 \: ev}}}$
