Practice CBSE Class 12 Inorganic Chemistry in the app →Silver ($Z = 47$) has a fully-filled $4d^{10}$ configuration in its ground state. Despite this, it is still clAmong the 3d-series transition metals, the element that exhibits the largest number of oxidation states is:The 'spin only' magnetic moment $\mu$ (in Bohr magnetons) of a transition metal ion with $n$ unpaired d-electrThe spin-only magnetic moment of $\mathrm{Fe}^{3+}$ (ground state) is approximately:$\mathrm{Cu}^+$ ion is unstable in aqueous solution because it:The contraction in atomic radii along the lanthanoid series ($\mathrm{La}$ to $\mathrm{Lu}$) is called lanthanThe actinoid contraction is greater than the lanthanoid contraction because:Zinc has the lowest enthalpy of atomisation in the first transition series because:Highest oxidation states of transition metals are typically observed only in their:Among $\mathrm{Cr}^{2+}$ and $\mathrm{Fe}^{2+}$, the stronger reducing agent in aqueous solution is:
