• form coloured ions and compounds • form ions with different oxidation numbers • form ions with incompletely fi lled d-orbitals. transition elements have variable oxidation states in terms of the similarity in energy of the 3d and the 4s sub-she...
Transition metals and many of their compounds show paramagnetic behaviour B The enthalpies of atomisation of the transition metals are high C The transition metals generally form coloured compounds. D Transition metals and their many compounds act as good catalyst. Video Solution Struggling With D & ...
Why do transition metals generally give colored compounds in a solution? What are some factors that influence the color of transition metal complexes? Describe why most of the compounds formed by transition elements are coloured. What happens when metals and non...
Most of the compound of transition elements are coloured due to the presence of unpaired electrons in d-subshell of transition metal ions. It can be explained with the help of crystal filed theory. For example, in an octahedral complex [Ti(H(2)O)(6)]^(3+
Explain giving reasons:(i) Transition metals and many of their compounds show paramagnetic behaviour.(ii) The enthalpies of atomisation of the transition metals are high.(iii) The transition metals generally form coloured compounds.(iv) Transition metals and their many compounds act as good catalyst...
(chemistry) any of the group or metallic elements that have an incomplete inner ( d ) electron shell; they have multiple valencies and form coloured compounds and stable complex ions; the elements scandium to copper and those lying below them in the periodic table [..] + Add translation Eng...
4 (a)Explain why compounds of transition elements are usually coloured.[3](b)Coppe is used to make alloys such as brass. The percentage of copper in a sample of brass can be determined by dissolving the sample in concentrated nitric acid and reacting the mixture with potassium iodide. The ...
(alsotransition element) (chemistry) one of the group of metals in the centre of theperiodic table(= a list of all the chemical elements)that form colouredcompoundsand often act ascatalysts(= substances that make chemical reactions happen faster) ...
Besides, transition metal elements can form different compounds with a variety of colours. That is mainly because, these elements can have different oxidation states which are very colourful. These different oxidation states of the chemical element can have different colours. And, these colours arise...
