8 questions from the practice bank, spread across the chapter's topics. The full set is in the app.
The electrical conductivity of metals ranges from about:
Answer: B. 10⁴ to 10⁷ Ω⁻¹ m⁻¹
Why: Insulators have very low values and semiconductors lie in between.
Graphite, unlike diamond, is a good conductor of electricity because:
Answer: C. each carbon has a free (delocalised) electron in the layered structure
Why: The carbons are sp² hybridised, with one electron in each p orbital.
The number of atoms per unit cell in a simple cubic lattice is:
Answer: D. 1
Why: Eight corners, each shared by eight cells.
Silicon doped with arsenic (group 15) becomes:
Answer: C. an n-type semiconductor
Why: Each arsenic atom provides one extra electron.
Which of the following is an amorphous solid?
Answer: B. glass
Why: Glass is a supercooled liquid with only short-range order.
The packing efficiency of a simple cubic structure is:
Answer: A. 52.4%
Why: It is the least efficient of the cubic arrangements.
The magnetic behaviour of a substance with all electrons paired is:
Answer: D. diamagnetic, being weakly repelled by a magnetic field
Why: Examples are NaCl, benzene and water.
Which of the following is a property of crystalline solids?
Answer: A. a sharp melting point and a long-range order
Why: Amorphous solids soften over a range of temperature.
