Mn and Cr are in d block.
No 2 d block neutral elements can have same number of d
electrons.
P and Ar are in period 2.
So, they will not have any d electrons.
So, both have 0 d electrons.
Br and Kr are in p block and in same period.
They will have same number of d electrons.
Ni and Cu are in d block.
No 2 d block neutral elements can have same number of d
electrons.
Answer: option 2 and 3

20.) Using orbital diagrams, determine the number of unpaired electrons in each of the following atoms. Start with the noble-gas core designation in the first box and then enter electron arrows. Enter your answer using UP to indicate an upwards pointing arrow, DOWN to indicate a downwards pointing arrow, UP/DOWN to indicate two arrows(electrons) in the same orbital, and BLANK to indicate no arrows. Designate unpaired electrons as UP arrows and keep all unpaired electrons and empty orbitals in the...
