Question

The total energy of electron in the third orbit of he+ ion is

Answer 1

Answer:

6.04J

Explanation:

As Bohr's energy =-13.6*z^2/n^2

and in case of He+ z=2 n=3

Answer 2

The total energy of electrons in the third orbit of$He^{+}$ ion is   $-2.421*10^{-19}$ J

Explanation:

The total energy of electron in the third orbit of Helium ion is calculated as :

Step 1:- Energy of hydrogen atoms calculated with this formula

$En =-\frac{13.6}{n^{2} } eV$ -------- 1

Step 2 :- Energy of hydrogen atom when the electron is in 3rd orbit

Then substituting the value  n=3 in equation (1)

$En =-\frac{13.6}{3^{2} } eV$

$En =-1.51 eV$

$1eV = 1.602 *10^{-19} J$

Now $En =$ $-2.421*10^{-19}$ J

The total energy of electron in the third orbit of Helium  ion is  $-2.421*10^{-19}$ J
