WebColoured compounds Transition metals have two distinctive properties. One property is that they can form coloured compounds. The other is that many transition metals such as iron... WebColoured compounds. If colour is caused by the absorption of certain wavelengths from white light, the question remains - how are these wavelengths absorbed? The colour in the transition metals (d-block) is usually due to the 'splitting' of the 'd' shell orbitals into …
WebMany alkali metal compounds are white in color and are colorless in solution, while the transition metal compounds have a wide variety of colors in their solid states and aqueous solution. Statement A is false. So, the correct answer is A: transition metals produce less colorful compounds than alkali metals. WebIn the first-row transition elements, all the elements except Zn form coloured ions. As these elements have incomplete d-orbital, some amount of energy is required to promote the electrons from lower energy level to higher energy level. This process exhibits …

They form coloured compounds and act as catalysts.
WebComplex ions containing transition metals are usually coloured, whereas the similar ions from non-transition metals aren't. That suggests that the partly filled d orbitals must be involved in generating the colour in some way. ... and an explanation of how this can be …
