  1. 1Who first ordered elements by atomic mass?
    1. AMendeleev
    2. BDalton
    3. CNewlands
  2. 2Who created the law of octaves for ordering elements?
    1. AMendeleev
    2. BDalton
    3. CNewlands
  3. 3Who created the modern periodic table?
    1. AMendeleev
    2. BDalton
    3. CNewlands
  4. 4True or false? The reason why Mendeleev's periodic table worked was because he left gaps for undiscovered elements which may have had similar properties.
    1. ARichtig
    2. BFalsch
  5. 5What is unusual about the pair of elements tellurium (Te, Z = 52) and iodine (I, Z = 53)?
    1. ATellurium has similar properties to the halogens and is placed with them, while iodine has similar properties to Group 6 and is placed with them
    2. BTellurium has a higher relative atomic mass than iodine
    3. CTellurium has 7 outer electrons although it is placed in Group 6, and iodine has 6 outer electrons but is placed in Group 7
  6. 6True or false? In the modern periodic table, elements are arranged by mass number.
    1. ARichtig
    2. BFalsch
  7. 7True or false? Larger atoms lose electrons more easily and gain electrons less easily than smaller atoms.
    1. ARichtig
    2. BFalsch
  8. 8Which of these are the most reactive in their respective groups?
    1. APotassium, Group 1
    2. BFluorine, Group 7

    4. DSodium, Group 1
    5. ERubidium, Group 1
    6. FBromine, Group 7
  9. 9Which of these are properties of alkali metals?
    1. AThey have a low density
    2. BThey form coloured compounds and solutions
    3. CThey form white compounds and colourless solutions
    4. DThey have high melting and boiling points
    5. EThey have low melting and boiling points
    6. FThey have a high density
  10. 10True or false? Caesium is less reactive than lithium as reactivity decreases going down the group.
    1. ARichtig
    2. BFalsch
