During the Bronze Age, which disadvantage resulted when smelted copper was contaminated with arsenic during toolmaking?

💡 Explanation

Arsenic impurities introduce brittleness because grain boundary segregation weakens the metallic bonds via embrittlement, therefore tools shatter more readily upon impact, rather than exhibiting ductility, which resists cracking and bending under stress.
