Textbook Question
Chapter 12.3, Problem 12.1.1PE
Consider the two-dimensional square lattice of Figure 12.4. The “packing effiency” for a two-dimensional structure would be the area of the unit cell, times 100%. What is the packing efficiency for a square lattice for atoms of radius a/2 that are centered at the lattice points?
a. 3.14%
b. 15.7%
c. 31.8%
d. 74.0%
e. 74.0%

Students have asked these similar questions
A certain half-reaction has a standard reduction potential Ered +1.26 V. An engineer proposes using this half-reaction at the anode of a galvanic cell that
must provide at least 1.10 V of electrical power. The cell will operate under standard conditions.
Note for advanced students: assume the engineer requires this half-reaction to happen at the anode of the cell.
Is there a minimum standard reduction
potential that the half-reaction used at
the cathode of this cell can have?
If so, check the "yes" box and calculate
the minimum. Round your answer to 2
decimal places. If there is no lower
limit, check the "no" box..
Is there a maximum standard reduction
potential that the half-reaction used at
the cathode of this cell can have?
If so, check the "yes" box and calculate
the maximum. Round your answer to 2
decimal places. If there is no upper
limit, check the "no" box.
yes, there is a minimum.
