Why is mn2 colourless

Subscribe to: Post Comments Atom. Featured Post Salicylic acid is a stronger acid than Benzoic acid. Bleaching powder is not a true compound but it is a mixed salt of calcium hypochlorite [Ca OCl 2 ]. The structure of crystalline solids is determined by packing of their constituents.

In order to understand the packing of the constituen We know that the Ligands which cause large degree of crystal filed splitting are termed as strong field ligands. Lux- Flood Acid-Base Concept:. The Lux-Flood concept is given by Lux in and supported by Flood in Lux-Flood concept is based on oxide ion acceptor and donor ten H 2 O where y is the total molar sulphur trioxide content.

I improved the formatting of your post by using MathJax for chemical formulae. For more information on how to do so yourself, check out the help center , this meta-post or this one. And there are even more hints available. I am Quark. It has to do with the selection rules governing d-d transitions in a metal complex: wwwchem. So there must be no electron with same spin in that orbital, to which the electron is being transited to?

Because if it were present it should have opposite spin which will violate Hund's rule? Show 1 more comment. Active Oldest Votes. Compare this image taken from Wikipedia , where a full list of authors is available: However, it is true that the colour is rather faint, and you need a white background to properly see it.

Improve this answer. Jan Jan For example if you added one more spin down electron to the lower level, then that electron could be promoted to the upper level, as long as it retains its spin state in the upper level no change in spin.

So, if we had 8 electrons, there would be a characteristic colour, right? Show 3 more comments. Sign up or log in Sign up using Google. Sign up using Facebook.
