The 20 questions

  1. What is a period in the Periodic Table?

    • A group of elements with the same colour
    • A horizontal row of elements
    • A list of elements in alphabetical order
    • A vertical column of elements

  2. What is a group in the Periodic Table?

    • A set of elements that are all liquids at room temperature
    • A set of elements that are all gases at room temperature
    • A horizontal row of elements that all have the same atomic mass
    • A vertical column of elements with similar properties

  3. Which group contains the noble gases?

    • Group 1
    • Group 2
    • Group 7
    • Group 0

  4. Which group contains the alkali metals?

    • Group 3
    • Group 7
    • Group 1
    • Group 0

  5. Which group contains the halogens?

    • Group 1
    • Group 4
    • Group 7
    • Group 0

  6. Where are most metals found in the Periodic Table?

    • On the far right, next to the non-metals
    • Only in the bottom row, below all the other elements
    • On the left and in the middle
    • Only in the top row of the table, across its whole width

  7. Where are the non-metals found in the Periodic Table?

    • Only in the top period
    • On the far left in Group 1
    • In the middle of the table only
    • On the right-hand side

  8. How many periods does the Periodic Table have?

    • Five
    • Eighteen
    • Seven
    • Nine

  9. Elements in the same group have the same number of what in their outer shell?

    • Neutrons
    • Protons
    • Molecules
    • Electrons

  10. Which group of elements is the most reactive metal group?

    • Group 0, the unreactive noble gases
    • Group 1, the alkali metals
    • Group 7, the halogen non-metals
    • Group 4, the carbon family

  11. Which element in Period 3 is a metal?

    • Chlorine
    • Sodium
    • Sulfur
    • Argon

  12. Which statement about metals and non-metals across a period is correct?

    • Elements change from metals on the left to non-metals on the right
    • Elements change from non-metals on the left to metals on the right
    • Elements are all metals across a period, from one end to the other
    • Elements are all non-metals across a period, from one end to the other

  13. Which group has elements that are all unreactive gases at room temperature?

    • Group 7
    • Group 0
    • Group 2
    • Group 1

  14. Which statement about the elements in Group 2 is correct?

    • Carbon, which is a non-metal found in Group 2 of the table
    • There is no non-metal in Group 2; all its elements are metals
    • Oxygen, which is a non-metal found in Group 2 of the table
    • Sulfur, which is a non-metal found in Group 2 of the table

  15. Why do elements in the same group react in a similar way?

    • They have the same colour when they are heated in a flame
    • They have the same number of neutrons in their nucleus
    • They have the same atomic number as one another always
    • They have the same number of outer electrons

  16. Which pattern is seen across the Period 2 elements from lithium to neon?

    • They are all metals with the same density and the same melting point
    • They are all liquids at room temperature, which is why they are grouped
    • They change from metals to non-metals and then to an unreactive gas
    • They become more metallic steadily from left to right across the period

  17. Which group contains elements with a full outer shell, meaning they rarely react?

    • Group 2
    • Group 0
    • Group 7
    • Group 1

  18. Which statement describes how the number of elements changes in a period?

    • Periods have different numbers of elements, so the rows differ in length
    • Every period contains exactly the same number of elements in each row of the table
    • Every period contains only metals in a single row of the table, with no gases
    • Every period contains only one element, which is repeated along the row

  19. Which group of elements is most likely to form negative ions?

    • Group 0, the noble gases
    • Group 7, the halogens
    • Group 2, the alkaline earth metals
    • Group 1, the alkali metals

  20. Which period of the Periodic Table contains the elements from lithium to neon?

    • Period 1
    • Period 2
    • Period 3
    • Period 4
