Assignment about types of alloys

Please watch the video below about alloys, then answer the questions below.

Name the two types of alloys illustrated above.

How is an alloy different from a pure metal?

Consider the two types of alloys. Based on the diagrams, define “substitutional” and “interstitial” in your own words.

Solids are most stable when the arrangement of atoms in the crystal lattice minimizes bond
length, maximizes bond strength, and maximizes the number of atoms “touching” one another—
in other words, when the atoms fill the space most efficiently.

Explain why an interstitial alloy would not form a stable crystal structure if the component
atoms were of similar size.

Sketch a diagram to illustrate your answer for question 5.

Explain why a substitutional alloy would not form a stable crystal structure if the component
atoms were different sizes.

Sketch a diagram to illustrate your answer for question 7.

Consider how the density of an alloy might compare to the density of the original metals.

Component atoms are similar size.		Interstitial Alloy
Component atoms are different sizes.		Substitutional Alloy

How is an alloy different from a pure metal?

Consider the two types of alloys. Based on the diagrams, define “substitutional” and “interstitial” in your own words.

One of the alloys in Model 1 tends to form when elements with similar sized atoms are melted
together and allowed to cool. The other type forms when elements with very different sized atoms
are combined. Match the descriptions below with each type of alloy.

Explain why an interstitial alloy would not form a stable crystal structure if the component
atoms were of similar size.

Sketch a diagram to illustrate your answer for question 5.

Explain why a substitutional alloy would not form a stable crystal structure if the component
atoms were different sizes.

Sketch a diagram to illustrate your answer for question 7.

Would substitutional alloys tend to have a density similar to, significantly greater than or
significantly less than the pure metal?

Would interstitial alloys tend to have a density similar to, significantly greater than or
significantly less than the pure metal?
