1. Which are the properties of alkali metals (group 1)?

  • They are very reactive, low density, very soft, melt and boil at low temperature, conduct electricity
  • They are very reactive, low density, very soft, melt and boil at low temperature and they have 7 electrons in their outer shell, don
  • They are very reactive, high density, very soft, melt and boil at low temperature, dont conduct electricity

2. Which are the properties of the halogens (group 7)?

  • low melting and boiling points, good conductors of heat and electricity
  • low melting and boiling points, bad conductors of heat and electricity
  • high melting and boiling points, bad conductors of heat and electricity
  • high melting and boiling points, good conductors of heat and electricity

3. What happens as you move down group 7?

  • more reactive, higher melting and boiling points
  • less reactive, higher melting and boiling points
  • less reactive, lower melting and boiling points
  • more reactive, lower melting and boiling points

4. What happens as you move down group 1?

  • bigger atoms, more reactive, lower density, lower melting and boiling points
  • bigger atoms, more reactive, higher density, lower melting and boiling points
  • bigger atoms, more reactive, lower density, higher melting and boiling points
  • bigger atoms, more reactive, higher density, higher melting and boiling points

5. What are the properties of the transition elements?

  • poor conductors of heat and electricity, very dense, strong, less reactive but denser and stronger than group 1 metals
  • good conductors of heat and electricity, very dense, strong, less reactive but denser and stronger than group 1 metals
  • good conductors of heat and electricity, very dense, strong, less reactive but denser and weaker than group 1 metals
  • good conductors of heat and electricity, very dense, strong, more reactive but denser and stronger than group 1 metals
