What are interstitial compounds? Why do these compounds have higher melting points than corresponding pure metals? |
|
Answer» Solution :(1)The interstitial compounds of the transition metals are those which are formed when small atoms like H, C or N are trapped INSIDE the interstitial vacant spaces in the CRYSTAL LATTICE of the metals. (2) Since metal-non-metal bonds in the interstitial compounds are stronger than metal-metal bonds in pure metals, the compounds have very high MELTING points, higher than the pure metals. |
