FREE Expert Solution

In this problem, we are asked to find if the alloy PdB0.15 is a substitutional alloy or an interstitial alloy.

An alloy is a substance that contains a mixture of elements and possesses some metallic properties.

Alloys are classified into two types: interstitial or substitutional

  • Interstitial alloy is where some of the host metal atoms have been replaced by other metal atoms that have a similar size

  • Substitutional alloy is where the empty spaces between the host metal atoms have been taken up by smaller metal or nonmetal atoms.

To answer this problem, we must know the size of the atoms of each component in an allow.
