The metal which has the highest work function in the following is
- A Cesium
- B Sodium
- C Aluminium
- D Platinum
Answer & Solution
Correct Answer
(D) Platinum
Step-by-step Solution
Detailed explanation
Work function is the minimum energy required by an electron to escape from the metal surface. It depends on the properties of the metal and the nature of the surface. The work function is higest for Platinum with value of 5.65 eV and it is lowest for Cesium with value…
