Alchemists were medieval scholars and philosophers who were the forerunners of modern-day chemists. Many tried repeatedly to transform lead (atomic number 82) into gold (atomic number 79). Explain why they never succeeded.
Atomic Number
The quantity of protons present in an atom's nucleus, which dictates the element's chemical characteristics and position within the periodic table.
Alchemists
Ancient practitioners who sought to transform base metals into noble metals, such as gold, and to discover a universal cure for disease and a way of extending life.
Lead
A heavy metal element with the symbol Pb, known for its malleability, poor conductivity, and various uses and health impacts.
- Explain the concept of chemical stability and the role of electron configuration in the reactivity of atoms.

Final Answer :
Medieval alchemists understood the transformative processes of heat and other simple chemical reactions but lacked a fundamental understanding of matter at the atomic level. Specifically, they were attempting to remove protons from lead (Pb) to create gold (Au), a process that would be incredibly difficult and require massive quantities of energy as lead represents a particularly stable element.
