4QuestionStructure and Layout of the Periodic TableAssessment Practice
5 marks~8 minCriterion C
A student claims: "Elements in the same group have identical properties."
The data below shows atomic radius (pm — a measure of atom size) and melting point (°C) for two sets of elements.
Group 1 — Li, Na, K
Period 3 — Na, Mg, Al
The data below shows atomic radius (pm — a measure of atom size) and melting point (°C) for two sets of elements.
Group 1 — Li, Na, K
| Atomic radius (pm) | 152 | 186 | 227 |
|---|---|---|---|
| Melting point (°C) | 180 | 98 | 64 |
Period 3 — Na, Mg, Al
| Atomic radius (pm) | 186 | 160 | 143 |
|---|---|---|---|
| Melting point (°C) | 98 | 650 | 660 |
a
Identify one trend in atomic radius for Group 1 elements as you move from Li to K. [1]
b
Describe how melting point changes across Period 3 (Na → Mg → Al), using the data to support your answer. [2]
c
Compare the patterns in Group 1 and Period 3, and use this to evaluate whether the student's claim is valid. [2]
