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) $Ti^{3+}$
(b) $Cr^{2+}$
(c) $Co^{2+}$
(d) $Ni^{2+}$
Show Answer
Solution:
- (d) Magnetic moment $=2.84$ B.M. This indicates that 2 unpaired electrons are present.
Number of unpaired electrons $(n)=2$
Hence, $Ni^{2+}$ gives magnetic moment of 2.84 B.M.
