Current Question (ID: 18848)

Question:

$\text{The addition of non-metals like B and C to the interstitial sites of a transition metal increases}$

Options:

1. $\text{Ductility}$
2. $\text{Melting Point}$
3. $\text{Shining}$
4. $\text{Conductivity}$

Solution:

$\text{HINT: High melting point than pure metal}$ $\text{Explanation:}$ $\text{In the crystal lattice of transition metal, small atoms like C, H, O, etc are trapped. Such compounds are called interstitial compounds. The property of interstitial compounds is better than the pure metal.}$ $\text{The interstitial compounds have high melting points than those of pure metals. Hence, option second is the correct answer.}$
