Which of the following elements can form interstitial alloy with transition elements?
Correct answer: D. All of these
- A. Si
- B. P
- C. B
- D. All of these
Explanation
Silicon and boron are both nonmetals that are smaller than most transition metals, so they can fit into the interstitial sites in the lattice of a transition metal. Silicon is particularly useful in forming interstitial alloys with iron (Fe) and other transition metals. Boron is often used to form interstitial alloys with titanium (Ti), which can improve the hardness and strength of the resulting alloy. Phosphorus is also a nonmetal that is smaller than many transition metals, so it can fit into the interstitial sites of a metallic crystal lattice. Phosphorus is often used to form interstitial alloys with iron (Fe), which can improve the strength and ductility of the alloy. Therefore, the correct answer to the question is "all of these" - all of the elements listed (silicon, phosphorus, and boron) can form interstitial alloys with transition metals.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
