Q1
Easy
In which type of crystalline structure do atoms occupy the corners of a cube and the center of each face?
A.
Simple Cubic
B.
Body-Centered Cubic
C.
Face-Centered Cubic
D.
Hexagonal
Show Answer & Explanation
Correct Answer: C
The face-centered cubic (FCC) structure has atoms at the corners and at the center of each face.
Q2
Easy
Which of the following properties is characteristic of ionic crystals?
A.
Conduct electricity in solid state
B.
Brittle and hard
C.
High malleability
D.
Dissolve in organic solvents
Show Answer & Explanation
Correct Answer: B
Ionic crystals are generally hard and brittle due to the strong electrostatic forces between ions.
Q3
Easy
What is the unit cell type of diamond?
A.
Simple Cubic
B.
Face-Centered Cubic
C.
Body-Centered Cubic
D.
Cubic with diamond structure
Show Answer & Explanation
Correct Answer: D
Diamond has a cubic crystal system but is structured in a unique manner that gives it distinct properties.
Q4
Medium
If the edge length of a face-centered cubic (FCC) unit cell is 'a', what is the radius of the atoms in the lattice?
A.
a/2
B.
a/√2
C.
a/√4
D.
a/√3
Show Answer & Explanation
Correct Answer: B
In an FCC unit cell, the atoms touch along the face diagonal, which is √2a. Thus, the radius (r) = (√2a)/2 = a/√2.
Q5
Medium
What type of unit cell is characterized by a three-dimensional arrangement where atoms are located at each corner and the center of each face?
A.
Face-Centered Cubic
B.
Body-Centered Cubic
C.
Simple Cubic
D.
Hexagonal Close-Packed
Show Answer & Explanation
Correct Answer: A
In a Face-Centered Cubic (FCC) unit cell, atoms are present at each of the eight corners and the centers of all six faces of the cube.
Q6
Medium
In a crystalline solid, if the coordination number is 4, which type of structure is most likely observed?
A.
Cubic
B.
Tetrahedral
C.
Octahedral
D.
Trigonal
Show Answer & Explanation
Correct Answer: B
A coordination number of 4 typically corresponds to a tetrahedral arrangement of atoms in crystal structures.
Q7
Medium
Which type of crystal lattice is characterized by atoms at the corners and one atom at the center of the cube?
A.
Simple Cubic
B.
Body-Centered Cubic
C.
Face-Centered Cubic
D.
Diamond Cubic
Show Answer & Explanation
Correct Answer: B
In a Body-Centered Cubic (BCC) lattice, there are atoms located at the corners of the cube and one atom at the center.
Q8
Hard
In a face-centered cubic (FCC) structure, what is the coordination number of the atoms?
A.
4
B.
6
C.
8
D.
12
Show Answer & Explanation
Correct Answer: D
In a face-centered cubic structure, each atom is in contact with 12 other atoms, making the coordination number 12.
Q9
Hard
Which of the following statements is true regarding the unit cell of a body-centered cubic (BCC) lattice?
A.
It has one atom at each corner of the cube.
B.
It has one atom at the center and one at each face.
C.
It has a total of 2 atoms per unit cell.
D.
Its coordination number is 8.
Show Answer & Explanation
Correct Answer: C
A body-centered cubic lattice has 2 atoms per unit cell: 1 from the center and 1/8 contribution from each of the 8 corners.
Q10
Hard
Which of the following is not a characteristic property of crystalline solids?
A.
Anisotropy
B.
Definite melting point
C.
Long-range order
D.
Isotropic nature
Show Answer & Explanation
Correct Answer: D
Crystalline solids exhibit anisotropy due to their long-range order, meaning their properties differ based on direction, unlike isotropic materials.
