Answer:
The answer for this is that for converting lead into gold we need to change the amount of protons in lead which with help in converting it to the gold.
Explanation:
Lead (atomic number is 82) and gold (atomic number is 79) are characterized by the protons density which they possess as components. Changing the factor involves modification of the amount of the atom (proton). It is difficult to change the amount of protons in an atom through any chemical Reaction.
Physics can, therefore, be used to attach or subtract protons and thereby turn one part into another. Since lead is solid, it is pushed out and the gold is surpassed.
