The dand fblock elements - Result Question 4

####4. Magnetic moment 2.84 B.M. is given by:-

(At. nos, Ni=28,Ti=22,Cr=24,Co=27 ) [2015]

(a) Ti3+

(b) Cr2+

(c) Co2+

(d) Ni2+

Show Answer

Solution:

  1. (d) Magnetic moment =2.84 B.M. This indicates that 2 unpaired electrons are present.

Number of unpaired electrons (n)=2

Hence, Ni2+ gives magnetic moment of 2.84 B.M.
