Given conditions ⇒
Ionization Energy = -13.6 eV atom
= 13.6 × 1.6 × 10⁻¹⁹ J/atom. 
= 2.176 × 10⁻¹⁸ J/atom. 

We know that He ion is single electron species which resembles the Hydrogen. 

Now, Using the Expressions which gives the energies of the stationary orbits of the Hydrogen like ions. 

∴ Energy required = (I.E. )Z²/n²

Where, 
Z = 2 and
n = 1 atom.

  ∴ E = (2.176 × 10⁻¹⁸)(2)²/(1)²
        = 8704 × 10⁻¹⁸ J



Hope it helps.
