Question

The energy of hydrogen atom in its ground state is -13.6 eV. The energy of the level corresponding to n = 5 is: (A) - 0.54 eV (B) -5.40 eV (C) - 0.85 eV (D) - 2.72 eV

En =E1 (Z2/n2) E5 =-13.6 ×((1)2/(5)2)=-0.54 eV

Q. The energy of hydrogen atom in its ground state is $- 13.6 e V$ . The energy of the level corresponding to $n = 5$ is:

$- 0.54 e V$

$- 5.40 e V$

$- 0.85 e V$

$- 2.72 e V$

$E_{n} = E_{1} \frac{Z ^{2}}{n ^{2}}$
$E_{5} = - 13.6 \times \frac{( 1 ) ^{2}}{( 5 ) ^{2}} = - 0.54 e V$

Q. The energy of hydrogen atom in its ground state is −13.6eV. The energy of the level corresponding to n=5 is:

−0.54eV

−5.40eV

−0.85eV

−2.72eV
