Question

Electromagnetic radiation of wavelength 242 nm is just sufficient to ionize the sodium ato
What is the ionisation energy of sodium per atom​

Answer 1

Answer:

The ionization energy of sodium people possessed by the government to 242 nm. It is E=

hc/lemda=6.626×10-^34,Js×3×10^8/242×10-^9=8.21×10^-19

the ionization energy per mole is 8.21×10^-19×6.023×10^23=494000J=494kJ
