Which of the following structures has the highest packing efficiency? (2019)
Step 1: Understand what packing efficiency means. It refers to how much space is filled by atoms in a crystal structure compared to the total space available.
Step 2: Learn about different types of crystal structures. The common ones are simple cubic, body-centered cubic (BCC), and face-centered cubic (FCC).
Step 3: Know the packing efficiency values for each structure: Simple cubic has about 52%, BCC has about 68%, and FCC has about 74%.
Step 4: Compare the packing efficiencies. FCC has the highest packing efficiency at approximately 74%.
Step 5: Conclude that the face-centered cubic (FCC) structure has the highest packing efficiency among the options given.
