Question

why do the transistor metal ions exhibit characteristic colours in aqueous solutions. Explain by giving examples? ​

Answer 1

Answer:

It is due to d-d transitions of the outermost electrons, they get easily excited and give a characteristic colour in aqueous solution. Hey !! Most of the transition metal ions exhibit characteristic colours in aqueous solution because of d-d transitions, as they have maximum number of unpaired electrons

Answer 2

When light falls on a transition element compound, electrons in lower energy d-orbital absorb some light (of wavelength within visible range) and are prompted to the higher energy d-orbital. ... Thus, ions of transition elements are coloured.
