Question

Which of the following is a definition for an interstitial alloy?

a
an alloy in which the atomic sizes of the components are different
b
an alloy in which the atoms of the components in an alloy are about the same size
c
an alloy in which some of the atoms of the components are about the same size and some are different
d
a metal in which all of the atoms are of the same element

Answer 1

c

Step-by-step explanation:

An interstitial compound or interstitial alloy is a compound that is formed when an atom of sufficiently small radius sits in an interstitial “hole” in a metal lattice. Examples of small atoms are hydrogen, boron, carbon and nitrogen. These compounds are important industrially, for example some transition metal carbides and nitrides.
