Transition metals are heavily alloyed to dramatically enhance their physical properties such as hard — d and f Block Elements Chemistry Question

💡 Solution & Explanation

All listed alloy compositions are standard and correct. Brass is an alloy of $Cu$ and $Zn$. Bronze is an alloy of $Cu$ and $Sn$. Gun metal is a specific ternary alloy comprising $Cu$ ($88\%$), $Sn$ ($10\%$), and $Zn$ ($2\%$). Mischmetal is an inner transition metal alloy consisting of $\approx 95\%$ lanthanides (mostly $Ce$ and $La$) and $\approx 5\%$ $Fe$.
