SUMMARY
The longest wavelength of electromagnetic radiation that can ionize an atom of lithium (Li) with an ionization energy (IE1) of 520.1 kJ/mol can be calculated using the formula λ = hc/E. The energy must be converted from kJ/mol to joules for accurate calculations. The constants used are Planck's constant (h = 6.626 x 10^-34 J*s) and the speed of light (c = 3.00 x 10^8 m/s). A common confusion arises from unit conversions, particularly when transitioning from kJ to J.
