True / False :
(A) No. of electrons having l = 0 in Pd is 10.
(B)The value of Zeff. for 3rd electron of Cr & Mn is same as no. of electron in 'd' subshell are same.
(C) Multiplicity of Fe is equal to Ni2+
a. False, l is equal to 0 only for an s orbital and in Pd, only four s orbitals (1s, 2s, 3s and 4s) are filled
b. false because the number of protons in Cr and Mn are both different, so effective nuclear charge for 3rd e- in both will be different.
c.true, because they both have same number of d-electrons (that is 8), so multiplicity for both is the same.
