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

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) of Ni^(2+) would be (At. No. of Ni = 28)
