# Question) If 13.6 eV energy is required to ionize the hydrogen atom, then the energy required to remove an electron from n = 2 is:

## If 13.6 eV energy is required to ionize the hydrogen atom, then the energy required to remove an electron from n = 2 is:

Option 1) 10.2 eV

Option 2) 0 eV

Option 3) 3.4 eV

Option 4) 6.8 eV

E=3.4 eV

As we all know that; Ionization energy –

Wherein, Energy required to move an electron from ground state to $n= \infty$

For an electron to remove from

n = 2

ni = 2

$E_{0}=13.6\ eV$     &    z = 1

The correct option is 3.4 eV, the 3rd option.
