Answer 1

Explanation:

For Hydrogen and Hydrogen like atoms,

\(E_n=-13.6\frac{Z^2}{n^2}eV\)

where \(Z\) is atomic number

n is number of atom.

Here \(Z=1,n=1\)

\(E_n=-13.6\frac{Z^2}{n^2}eV=-13.6eV\)

This is the ground state energy of Hydrogen atom.

Now, the minimum energy required to to convert is Ionization Energy.

Ionization Energy\(=-\text{Ground state energy}\)

\(I.E.=E_1=-(-13.6)eV=13.6eV\)

Hence, the correct answer is Option-1=13.6eV.
