Worked practice questions

The modern periodic law states that the physical and chemical properties of elements are periodic functions of:

  1. Atomic mass
  2. Atomic radius
  3. Atomic number
  4. Number of neutrons
Show answer and solution

Correct answer: C. Atomic number

Modern (Moseley's) periodic law: properties of elements are periodic functions of their **atomic number** ($Z$). This replaced Mendeleev's original law which was based on atomic mass. Why atomic number wins: it explains chemistry better (electronic structure follows $Z$, not mass) and resolves Mendeleev's anomalies (the Ar/K and Te/I pairs whose mass-order disagrees with chemistry-order).

Elements of the modern periodic table are classified into how many blocks based on the differentiating electron?

  1. 2 (s and p)
  2. 4 (s, p, d, f)
  3. 3 (s, p, d)
  4. 5 (s, p, d, f, g)
Show answer and solution

Correct answer: B. 4 (s, p, d, f)

**Four blocks** based on which subshell the differentiating electron enters: - **s-block**: Groups 1 and 2 (Li, Na, K, Be, Mg, Ca, etc.) - **p-block**: Groups 13 to 18 (B, C, N, O, F, halogens, noble gases) - **d-block**: Groups 3 to 12 (transition metals) - **f-block**: Lanthanides and actinides (separated below the main table) No g-block has been confirmed experimentally yet, though it's predicted for superheavy elements ($Z > 120$).

Across a period from left to right, the atomic radius generally:

  1. Decreases
  2. Remains constant
  3. Increases
  4. First increases then decreases
Show answer and solution

Correct answer: A. Decreases

Atomic radius **decreases** from left to right across a period. Why: nuclear charge ($Z$) increases by 1 as you move right, pulling electrons closer. The added electron enters the same shell so screening barely increases — the net effect is stronger attraction and smaller radius. Across period 2: Li (152 pm) → Be → B → C → N → O → F (72 pm). Roughly halves. Down a group, atomic radius *increases* (electrons go into higher principal shells, further from nucleus).
