Which element from following is used in photoelectric cells?

Options

  1. ALi
  2. BBe
  3. CCs
  4. DMg

Correct answer

C. Cs

Step-by-step solution

Cesium (Cs) is the element used in photoelectric cells: Explanation: Cesium is the preferred metal for photoelectric cells because it can easily convert sunlight into electricity. It has a low ionization energy and is the most electropositive element. The amount of energy required to eject electrons from a cesium surface is relatively small, only 206.5 kJ/mol.
