Question

calculate the energy associated with the first orbit of He+. what is the raduis of this orbit ???​

Answer 1

Answer:

Explanation:

calculate the energy associated with the first orbit of He⁺

   $E = - 13.6\frac{z^{2} }{n^{2} }$

  $= - 13.6$ × $\frac{2^{2} }{1^{2} }$ = 54.4 ev

Radius of orbit r = 529 × $\frac{n^{2} }{z}$ nm

= $529$ × $\frac{12}{2}$

= 264.5 nm
