Photographic plates are coated with a thin film of:
Correct answer: D. AgBr (silver bromide)
- A. AgNO3 (silver nitrate)
- B. AgI (silver iodide)
- C. AgCl (silver chloride)
- D. AgBr (silver bromide)
Explanation
Key properties of silver halides in photography:Silver halides (AgX, where X represents a halogen) are light-sensitive compounds.When exposed to light, silver ions (Ag+) in these compounds are reduced to metallic silver (Ag), creating a latent image on the photographic plate.Different silver halides have varying sensitivities to light:

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
