Which element has a mass of 24? Chromium Why are lanthanides Coloured? Lanthanides or more precisely lanthanides ions are coloured mainly because of their partly filled f orbitals. This allows a certain wavelength from the visible region of the spectrum to be absorbed which leads to the formation of f-f transition. Is lanthanides are Colourless? […]
