How can the ionization energy of sodium be calculated knowing that the value of the wavelength at the Start of the continuum in the emittion spectrum is 242nm?
1 Answer
The ionization energy is
Explanation:
The value of the wavelength at the start of the continuum represents the ionization energy: the energy needed to remove a

This is the ionization energy for one sodium atom.
For 1 mol of sodium atoms,
