Why does Chromium have such a weird electron …
2008/9/5· We were writing out the electronic configuration of the first 30 elements and I noticed something weird when I came to Chromium. Vanadium has the electron arrangement 2,8,11,2 and the electronic configuration 1s 2,2s 2, 2p 6, 3s 2,3p 6,4s 2,3d 3 - so by the
Calcium - Wikipedia
Calcium is a chemical element with the syol Ca and atomic nuer 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air.Its physical and chemical properties are most similar to its heavier

This gives calcium an outer-shell electron configuration corresponding to that of beryllium and magnesium. Beginning with the transition metal scandium (atomic nuer 21), additional electrons are added successively to the 3 d subshell.
ELECTRONIC STRUCTURES OF IONS - chemguide
2020/8/9· The electronic structure of d-block ions Here you are faced with one of the most irritating facts in chemistry at this level! When you work out the electronic structures of the first transition series (from scandium to zinc) using the Aufbau Principle, you do it on the basis that the 3d orbitals have a higher energy than the 4s orbital.

condensed electron configuration for Mn2+? | Yahoo …
2010/7/28· why is the condensed electron configuration for Mn2+ [Ar]3d^5 and not [Ar]4s^2 3d^3 thanks :) The reason is that the 3d shell is a bit closer to the nucleus (with lower overall energy) than the 4s shell. For manganese, the 4s^2 electrons are its valence electrons and
electronic structures of atoms - chemguide
We are working out the electronic structures of the atoms using the Aufbau ("building up") Principle. So far we have got to calcium with a structure of 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2. The 4s level is now full, and the structures of the next atoms show electrons
