Any process of chemical decay of metals due to the action of the surrounding medium is called?
Correct answer: C. Corrosion
- A. Activation
- B. Enamelling
- C. Corrosion
- D. Coating
Explanation
Option A : The process where something is prepared or excited for a subsequent reaction. Option B : Enamelling is the process of applying a thin coat of finely ground glass to metal. Option: C Corrosion is when a refined metal is naturally converted to a more stable form such as its oxide, hydroxide or sulphide state this leads to the deterioration of the material. Corrosion is the chemical decay of metals due to the actions of the surrounding medium. Option D : The coating is a layer of any substance spread over a surface.

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.
