Vedclass · Answer

(B) $(1)$ Manganese $(Mn)$ has the electronic configuration $[Ar] 3d^5 4s^2$ and can exhibit oxidation states up to $+7$ (e.g.,in $KMnO_4$). This statement is correct.$(2)$ Zinc $(Zn)$ has a completely filled $3d^{10}$ configuration,so it cannot form colored ions. This statement is incorrect.$(3)$ In $[CoF_6]^{3-}$,$Co$ is in the $+3$ oxidation state $(3d^6)$. $F^-$ is a weak field ligand,so it does not cause pairing of electrons. Thus,it has $4$ unpaired electrons and is paramagnetic. This statement is incorrect.$(4)$ Scandium $(Sc)$ has the configuration $[Ar] 3d^1 4s^2$ and exhibits only a $+3$ oxidation state. It cannot exhibit a $+4$ state. This statement is incorrect.$(5)$ Zinc $(Zn)$ has the configuration $[Ar] 3d^{10} 4s^2$ and exhibits only a $+2$ oxidation state due to the loss of $4s$ electrons. This statement is correct.Therefore,statements $(1)$ and $(5)$ are correct.
