Question

The ionization potential of a single-electron species is exactly $340 \text{ V}$. The atomic number ($Z$) of this species is:

Answer: C

💡 Solution & Explanation

The ionization energy of a single-electron species is $13.6 \times Z^2 \text{ eV}$. Setting $340 \text{ eV} = 13.6 \times Z^2$ gives $Z^2 = 340 / 13.6 = 25$. Therefore, $Z = 5$.
