The atomic number of an element whose differentiating electron enters in a d sub-shell
Answers
Answer:
If the differentiating electron enters into the d-orbital of penultimate shell, the elements are called 'd-block elements” The general electronic configuration of d-block elements is (n-1)d1-10ns0-2 (n= 4 to 7) d-block elements lie between s & p block elements. all of these elements are metals
Answer:
The order for filling orbitals according to Hund's rule and n+l rule is:
The order for filling orbitals according to Hund's rule and n+l rule is:1s,2s,2p,3s,3p,4s,3d....
Therefore d-orbitals are filled first for element with atomic number
Therefore d-orbitals are filled first for element with atomic number=2+8+8+2+1=21.
