Same atoms, different gossip — chemistry's way of proving arrangement beats quantity.
means The phenomenon where two or more compounds share the exact same molecular formula but differ in how their atoms are arranged, giving them different structures and often different properties.
from Coined from Greek 'isos' (equal) and 'meros' (part/share) — literally 'equal parts.' The term was introduced in the early 19th century as chemists like Berzelius worked to explain puzzling cases where distinct substances, with different behaviors, turned out to have identical elemental compositions. The word captures the paradox directly: equal in portions, yet not the same thing — the parts tally, but their arrangement tells a different story.
