Question 1 · 1 mark · Difficulty 1/3

A student studying the periodic table in her chemistry class at a school in Kingston, Jamaica, noticed that elements in the same vertical column had similar properties. What is the correct term for a vertical column in the periodic table?

  1. A period
  2. A group
  3. A series
  4. A block
Show answer & explanation
✓ Answer: B — A group
Award 1 mark for identifying that vertical columns are called groups. A is incorrect — a period is a horizontal row. C is incorrect — series is not the standard term used for columns. D is incorrect — blocks refer to sections of the table (s, p, d, f blocks), not individual columns.
Question 2 · 1 mark · Difficulty 1/3

In a bauxite processing plant in Guyana, aluminium is extracted from its ore. The element aluminium (Al) is located in Period 3 of the periodic table. How many electron shells does an aluminium atom have?

  1. 2
  2. 3
  3. 4
  4. 13
Show answer & explanation
✓ Answer: B — 3
Award 1 mark for recognising that the period number indicates the number of electron shells. A is incorrect — this would place the element in Period 2. C is incorrect — this would be Period 4. D is incorrect — 13 is the atomic number (number of protons), not the number of shells.
