How do transition metals conduct electricity and form colored compounds?
Quick Answer
Transition metals often conduct electricity well because their electrons can move easily through the metal lattice. Many of them also form colored compounds because electrons in partly filled d-orbitals absorb specific wavelengths of light.
The Full Story
Transition metals occupy the central block of the periodic table, including iron, copper, nickel, and gold. Their atoms can share and move electrons in ways that make them excellent conductors and useful structural materials. Many of their compounds have vivid colors, such as copper(II) sulfate’s blue and chromium compounds’ greens and reds. That color comes from electronic transitions, especially involving d-electrons and surrounding ligands.
