Multiple Choice

in an interstitial alloy atoms------ while they---------- in a substitutional alloy

• fit in between atoms, stick to the owter surface of metals

• are always removed, are always added

• fit in between atoms, replace atoms with similar radii

Multiple Choice

Many metals are alloyed in order to increase their strength.  Gold can be alloyed with many metals.  For example, gold (radius 144 pm) and silver (radius 144 pm) can be alloyed to form white gold.  Which of the following metals would be best to make a substitutional alloy with gold?

• Silver (radius 128 pm)

• Platinum (radius 175 pm)

• Palladium (radius 163 pm)

• Zinc (radius 139 pm)
