Answer:
ELECTROPLATING
Explanation:
In silver plating, object (iron spoon) to be electroplated is made cathode, metal to be used for coating (bar of silver metal) as anode and silver nitrate solution as electrolyte. When current passes, positive ions moved toward the cathode and thus silver is coated to the spoon.
The process of depositing a layer of any desired metal on another material, by means of electricity is called electroplating.

Answer:-
Electrons or Protons
Explanation:-
Atomic number (Z) is defined as:
>>“The total number of protons in the nucleus of an atom is called atomic number”. All atoms of an element have the same number of protons and electrons.
>>“The total number of protons in the nucleus or electrons revolving around the nucleus of an atom”.
Example:
For instance, Hydrogen has the Atomic number(Z) 1.
Helium has the atomic number 2.
Oxygen has the atomic number 8.
| Note | Atomic number is represented by “Z”. And some ppl don’t consider the 2nd definition it’s upto u to do both or the standard one.
