Q1
Easy
What is the coordination number of an atom in a simple cubic crystal lattice?
A.
6
B.
4
C.
8
D.
12
Show Answer & Explanation
Correct Answer: A
In a simple cubic lattice, each atom is surrounded by 6 other atoms, one at each face of the cube, giving it a coordination number of 6.
Q2
Easy
Which type of crystal lattice is characterized by the presence of atoms at the corners and one atom at the center?
A.
Body Centered Cubic
B.
Face Centered Cubic
C.
Simple Cubic
D.
Hexagonal Close-Packed
Show Answer & Explanation
Correct Answer: A
In a Body Centered Cubic (BCC) structure, there are atoms located at the eight corners of the cube and one atom at the center, defining its unique structure.
Q3
Easy
Which lattice type has the highest packing efficiency?
A.
Simple Cubic
B.
Body Centered Cubic
C.
Face Centered Cubic
D.
Hexagonal Close-Packed
Show Answer & Explanation
Correct Answer: C
The Face Centered Cubic (FCC) structure has the highest packing efficiency of 74%, which is greater than that of other lattice types like Simple Cubic and BCC.
Q4
Medium
Which crystal system is characterized by all sides being equal and all angles being 90 degrees?
A.
Cubic
B.
Tetragonal
C.
Orthorhombic
D.
Hexagonal
Show Answer & Explanation
Correct Answer: A
The cubic crystal system is defined by having equal-length sides and all angles equal to 90 degrees.
Q5
Medium
In a face-centered cubic (FCC) lattice, how many atoms are present in one unit cell?
A.
1
B.
2
C.
4
D.
8
Show Answer & Explanation
Correct Answer: C
In an FCC lattice, there are 8 corner atoms contributing 1/8 each and 6 face-centered atoms contributing 1/2 each, totaling to 4 atoms in one unit cell.
Q6
Medium
What type of crystal lattice has an octahedral void?
A.
Simple cubic
B.
Body-centered cubic
C.
Face-centered cubic
D.
Close-packed structures
Show Answer & Explanation
Correct Answer: C
The face-centered cubic (FCC) lattice has octahedral voids located at the center of the unit cell and at the edges.
Q7
Medium
In the context of crystal lattices, what is a unit cell?
A.
The smallest repeating unit that retains the properties of the crystal.
B.
The total number of atoms in a crystal.
C.
The geometric shape of the crystal.
D.
The arrangement of atoms in a solid.
Show Answer & Explanation
Correct Answer: A
A unit cell is defined as the smallest repeating unit in a crystal lattice that can be repeated in three dimensions to form the entire lattice.
Q8
Hard
Which type of crystal system has the highest symmetry?
A.
Cubic
B.
Hexagonal
C.
Tetragonal
D.
Orthorhombic
Show Answer & Explanation
Correct Answer: A
The cubic crystal system possesses the highest symmetry among all crystal systems, characterized by its three equal axes intersecting at right angles, allowing for maximum uniformity in structure.
Q9
Hard
If the density of a crystal is 10 g/cm³ and the molar mass is 80 g/mol, what is the number of atoms present in the unit cell of a body-centered cubic (BCC) lattice?
A.
2
B.
4
C.
1
D.
3
Show Answer & Explanation
Correct Answer: A
In a BCC lattice, the number of atoms per unit cell is 2. The density formula relates mass and volume: using the density (10 g/cm³) and molar mass (80 g/mol), the effective number of atoms can be calculated as (Density * Volume_Molar)/(Molar_Mass).
Q10
Hard
Which of the following statements correctly describes the coordination number for a simple cubic lattice?
A.
4
B.
6
C.
8
D.
12
Show Answer & Explanation
Correct Answer: B
In a simple cubic lattice, each corner atom is surrounded by 6 other atoms (one on each face), leading to a coordination number of 6, which defines how many nearest neighbors an atom has.
