Final answer:
The ionization energy for hydrogen can be determined using the Bohr equation. The ionization energy is 2.18 x 10^-18 J.
Step-by-step explanation:
The ionization energy for hydrogen can be determined using the Bohr equation. The Bohr equation is given by:
E = -R_H(1/n2), where E is the energy, R_H is the Rydberg constant for hydrogen (2.18 x 10-18 J), and n is the principal quantum number.
To calculate the ionization energy for hydrogen, we need to find the energy when n = 1 and when n = infinity. When n = 1, the energy is:
E = -2.18 x 10-18 J
When n = infinity, the energy becomes zero. Therefore, the ionization energy for hydrogen is the difference between these two energies:
Ionization energy = 0 - (-2.18 x 10-18 J) = 2.18 x 10-18 J
