Well.....I left one portion in this article...i don't know how to edit it..You can also find the magnetic property like which is diamagnetic in nature and which is paramagnetic....simply just remember DEPO ....means dia if even and para if odd.......if no. of electron are even like 20 18 16 14 12 ...then it will be diamagnetic and if no of electron are odd ...then it is paramagnetic....like 13 11 and so on.....this short method is applicable in all field except O2 and B2 ....i.e they both have even no of electron O2 = 16 and B2 = 10 ...but then also they are para in nature....so remember these two...and apply DEPO for others.....Solve for all the compounds given in rectangle in the figure ....For case of CN- => no. of electron is = 6 + 7 + 1 = 14 ( 1 due to -1 charge ) .....so it has 14 electron ..B.O = 3 and is diamagnetic in nature....I hope you get more help now from this....nudge me and post comments....what is in your mind
