What is the energy possessed by an electron whose principal quantum number is infinite ?

Explanation

To find the energy possessed by an electron whose principal quantum number (n) is infinite, we can use the formula for the energy of an electron in a hydrogen-like atom:

\[ E = -\frac{13.6 \, Z^2}{n^2} \]

Where:
- \( E \) is the energy of the electron,
- \( Z \) is the atomic number (for hydrogen, \( Z = 1 \)),
- \( n \) is the principal quantum number.
