Copper

Copper's symbol 'Cu' comes from 'cuprum,' the Latin name derived from Cyprus, where ancient Romans mined huge quantities of it. Copper was one of the first metals humans ever used — copper tools and jewelry date back over 10,000 years. The Statue of Liberty is covered in copper sheets, which is why she turned from shiny brown to her iconic green color over time (that green layer is called patina).

Copper is an excellent conductor of electricity, which is why electrical wiring in your house is made of copper. It is also naturally antimicrobial — bacteria die on copper surfaces, which is why some hospitals use copper doorknobs and railings. Copper is essential for your body too, helping form red blood cells and maintain healthy nerves.

Copper's symbol 'Cu' is a useful two-letter element in Spellement. It matches the start of words like 'cup,' 'cut,' and 'cure,' fitting into common English patterns. Its distinctive letter pairing makes it a fun and recognizable element for creative word spelling.
