Basic metals can be converted into gold by ?

Correct answer: C. Artificial nuclear radioactivity

  • A. Heating
  • B. Beating
  • C. Artificial nuclear radioactivity
  • D. Chemical reaction

Explanation

Changing one element into another requires nuclear transmutation, which changes the atomic nucleus and hence the atomic number. Heating and chemical reactions only alter physical state or chemical combinations, not one element into gold.
