The bonds generally formin compounds of Actinoids are:

Which one of the following statement is incorrect about transition elements?

$$M^{x+}$$ ion has magnetic moment 2.84 BM.Then 'x' is (Z of M=22)

Which of the following set of elements are Ferromagnetic in nature?

The spin only magnetic moment of $$[Cu(NH_3)_4]^{2+}$$ complex is:-

Which of the following complex is anion ?

In $$K_2Cr_2O_7$$, every $$Cr$$ is linked to:

The magnetic moment (spin only) of $$[NiCI_4]^{2-}$$ is:

$$CrO_4^{2-}$$ (yellow) $$\xrightarrow[{pH=Y}]{pH=X}$$ $$Cr_2O_7^{-2}$$ (orange)
The $$pH$$ values $$X$$ and $$Y$$ are respectively:

The magnetic moment of $$V(Z= 23), Cr (Z= 34)$$ and $$Mn (Z= 25)$$ are $$x, y, z$$. Hence:
