What is the typical effect of the addition of an interstitial element on the properties of a metal?
A)increase in malleability and corrosion resistance
B)increase in hardness and strength, decrease in ductility
C)decrease in melting point and increase in ductility
D)decrease in conductivity and increase in brittleness
E)increased surface luster

Question

Quizplus · Accepted Answer

The addition of an interstitial element typically leads to an increase in hardness and strength due to the distortion of the crystal lattice caused by the smaller interstitial atom. This can also result in a decrease in ductility. Malleability may or may not be affected depending on the specific interstitial element and its concentration in the metal. Corrosion resistance, melting point, conductivity, and brittleness are not directly related to the addition of an interstitial element. Increased surface luster is also not a typical effect.
