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+
(1) Why do transition metal ions possess a great tendency to form complexes? (2) The paramagnetic character in 3d-transition series elements increases up to Mn and decreases. View Solution Explain the following observations: (a) Azide ion (N3) react with 2− bromopentane thousand times ...
解析 Ans. Zinc, cadmium and mercury of group 12 have full d10 configuration ( d orbitals arecompletely flled ) in their ground state as well as in their common oxidation states and hence,are not regarded as transition metals 反馈 收藏 ...
It is in large part responsible for the lack of late transition metal complexes with terminal oxo ligands, and can explain some of the unusual chemistry of late metal alkoxide complexes.doi:10.1080/02603598808035790James M. MayerTaylor & Francis GroupComments on Inorganic Chemistry...
Why do transition elements form colored compounds? Why do transition metals generally give colored compounds in a solution? Why are some solutions colored? Give reasons why most of the compounds formed by transition elements are colored. Why can't the halide ions be oxidizing agents? Why do comp...
When transition metals become ions, what is their charge? A) 1+ B) 1- C) 2+ D) Each transition element has different possible charge What are the electron configurations for each of the following ions? You should use the noble-gas abbreviations: Te^{...
Most transition metals can form more than one simple positive ion. For example, iron forms both Fe2+ and Fe31ions and tin forms both Sn2+ and Sn4+ ions. Which is the smaller ion of each pair, and why? When a d-transition...

This has been referred to as the Beer-Lambert law [3] and can be expressed in the form of the equation below. Absorbance = log(I0/I) where I0 = incident intensity I = transmitted intensity This expression can be re-written as shown below. (1) Absorbance = abc where a = absorption...
Definition : d-block elements are defined as the elements in which the differentiating electron enters d-orbital of the penultimate shell i.e. (n-1) d-orbital where 'n' is the last shell. The general electronic configuration can be represented as, (n-1
