The element copper has 11 valence electrons, distributed amongst the outermost d and s orbitals. These electrons are the ones that engage in chemical reactions that involve photons corresponding to visible light. The inner electrons require far higher energies to liberate, and do not figure in chemical reactions.

en.wikipedia.org/wiki/D_electron_count

The d electron count is an effective way to understand the geometry and reactivity of transition metal complexes. The formalism has been incorporated into the two major models used to describe coordination complexes; crystal field theory and ligand field theory, which is a more advanced version based on molecular orbital theory.
