How to determine the hybridization of a complex compound in a easy way?
Generally d-block elements have tendency to form coordination compounds.
from at. no. 21 .i.e scandium to 30 zn
the configuration starts as: 4s2 3d1 to 4s2 3d10 except chromium and copper
1) First step should be to find the coordination no.
2) Second step should be: Determine the oxidation no. of metal.
3) And According to that start removing electrons from 4s2 shell then from 3d orbital.
The number of electrons in [ 40 19 k ] -1 is: (1) 19 (2) 20 (3)18 (4)40 Ans: 40
