1. Question 1

   Q1. What differentiates the work function of a metal from its ionization energy?

   • A) Work function applies to bulk metals, ionization energy to isolated atoms
   • B) Ionization energy is independent of temperature
   • C) Work function involves photons, ionization energy electrons
   • D) Both terms are equivalent

   Answer: Work function applies to bulk metals, ionization energy to isolated atoms

   Explanation: Work function is the minimum energy to eject a surface electron. Ionization energy applies to gaseous atoms. Option D is incorrect.
