6. What is inside of an atom's nucleus?

  • Just protons
  • Protons and neutrons
  • Protons and electrons
  • Just neutrons
  • Neutrons and electrons

7. How are elements arranged in the Periodic Table?

  • By colour
  • By name
  • By patterns
  • By atomic number

8. When are negative ions formed?

  • When atoms gain electrons
  • When an atom reacts with another atom
  • When atoms lose electrons
  • When atoms are told that they look ugly

9. What can more reactive halogens do?

  • Conduct electricity
  • Anything they want #FREEDOM
  • Displace less reactive halogens
  • React with everything

10. When are Group 1 elements more reactive?

  • When they have more electron shells
  • When they have less electron shells
  • When they have a bigger atomic mass
  • When they have a smaller atomic mass

11. How many electrons can the first shell hold?

  • 2
  • 8
  • 6
  • It changes depending on the atom

12. What does the formula of an ionic compound contain?

  • A balance of positive and negative ions
  • A mixture of positive and negative ions
  • Only positive ions
  • Only negative ions

13. What is a column in the Periodic Table called?

  • A group
  • A selection
  • A column
  • A period

14. How many electrons can the second shell hold?

  • 7
  • 8
  • It changes depending on the atom
  • 2

15. What do halogens react with?

  • Anything
  • Group 1 metals
  • Nothing
  • Group 3 metals

16. Why can't ionic compounds always conduct electricity?

  • They don't have enough ions
  • They can only do it when their ions are free to move
  • They can never conduct it
  • They don't always have the motivation

17. Do ionic compounds conduct electricity?

  • Yes
  • Yes, but only when they're dissolved in water or molten
  • No, only some of them do
  • Yes, but not when they're dissolved in water or molten

19. What is the electron arrangement linked to?

  • Its place in the Periodic Table
  • Its place in the Periodic Table and its reactivity
  • Its reactivity
  • Its colour

20. What does the proton number tell us?

  • The number of electrons
  • The atomic mass
  • What it reacts with
  • What group it is in
