The sping only maagentic mome ( in Bohr magneton , `M_C)` of ` Hi^(2+)` in aqueouse solution would be :

The spin-only magnetic moment [in units of Bohr magneton, (mu_(B) of Ni^(2+) in aqueous solution would be (atomic number of Ni=28)

The spin-only magnetic moment [in units of Bohr magneton, (mu_(B) of Ni^(2+) in aqueous solution would be (atomic number of Ni=28)

The "spin-only" magnetic moment [in units of Bohr magneton, (mu_B) ] or Ni^(2+) in aquenous solution would be : (At no. Ni = 28 ).

Assertion (A): The "spin only” magnetic moment [in units of Bohr magneton, ( mu_(B) )] of Ni^(2+) in aqueous solution would be (atomic number Ni= 28) 2.84 BM Reason (R): The metal ion has 2 unpaired electrons
