Resource summary

Question 1

Question
How many neutrons does a sodium atom have?
Answer
  • 1
  • 11
  • 12
  • 23

Question 2

Question
What subatomic particle causes atoms to have different isotopes?
Answer
  • neutron
  • electron
  • proton

Question 3

Question
How many electrons can the second shell be filled up to?
Answer
  • 2
  • 4
  • 6
  • 8

Question 4

Question
Which separation technique allows you to separate a liquid and a dissolved solid, but keep the liquid too?
Answer
  • chromatography
  • distillation
  • evaporation/crystallisation
  • filtration

Question 5

Question
This scientist figured out there was atoms contain a positive nucleus, by firing alpha particles at gold.
Answer
  • Rutherford
  • Bohr
  • Thomson
  • Einstein

Question 6

Question
When going down group 1, the reactivity increases.
Answer
  • True
  • False

Question 7

Question
Who is most often credited with being the creator of the modern periodic table?
Answer
  • Newlands
  • Mendeleev

Question 8

Question
Group 7 elements are commonly known as [blank_start]Halogens[blank_end]. They normally exist as [blank_start]pairs[blank_end] of atoms. They become [blank_start]less[blank_end] reactive down the group – because the [blank_start]outer[blank_end] shell is further from the nucleus so it is [blank_start]harder[blank_end] to gain an electron. They have higher melting and boiling points [blank_start]down[blank_end] the group. A more reactive halogen will [blank_start]displace[blank_end] a less reactive halogen.
Answer
  • Halogens
  • pairs
  • less
  • outer
  • harder
  • down
  • displace

Question 9

Question
Tick all the boxes that reference the typical/general properties of metals.
Answer
  • shiny
  • dense
  • ductile
  • malleable
  • brittle
  • dull
  • sonorous
  • conductor
  • insulator

Question 10

Question
[blank_start]Simple distillation[blank_end] is a method for separating the [blank_start]solvent[blank_end] from a [blank_start]solution[blank_end], leaving behind the [blank_start]solute[blank_end]. This method works because the solvent has a much lower [blank_start]boiling point[blank_end] than the dissolved solute. Heating the solution allows the solvent to [blank_start]evaporate[blank_end], and then it passes through a condenser, where it is cooled and condensed into a separate container. The [blank_start]solute[blank_end] does not evaporate and so it stays behind.

  • Simple distillation
  • Filtration
  • Crystallisation/evaporation
  • Fractional Distillation
  • Chromatography

Answer
  • 2.8.1
  • 2.4
  • 2.8
  • 2.8.6
