how many unpaired electrons are present in chromium?
607345
Electron configuration for chromium: [Ar] 4s1, 3d5. Six unpaired electrons.
774878
For example, the element P, has an atomic mass of 15. So the electron configuration is 1s^2, 2s^2, 2p^6, 3s^2, 3p^3 (The exponents add up tp 15). Once you figure out the electron configuration, you fill up the corresponding orbitals with electrons, any left with one is considered unpaired.

(e) Krypton (Kr): Atomic number = 36 . No of the unpaired particles will be 6 (since 1 electron is to be added to 4s & 5 electrons to be attached to 3d orbital.

There are 5 unpaired electrons in the Fe3+ ion. The reason for this is that Iron has the electron configuration Ar3d5.
240779
Now since we are given with Iron(II) we take out two electrons from the outermost orbit so as to give the iron a +2 charge. As evident from the configuration, in total there are 4 unpaired electrons. Using the same logic you can count the number of unpaired electrons for any ion.
