Copper is an element, so it doesn't have a "chemical formula" like a compound does. Its chemical symbol is Cu (atomic number 29).

Key facts:
- Symbol: Cu

- Common oxidation states: +1 (cuprous, Cu+) and +2 (cupric, Cu2+)

Common copper compounds and their formulas:
- Copper(I) oxide: Cu2O

- Copper(II) chloride: CuCl2

If you meant a particular copper compound, tell me which one and I’ll give the formula.
