    • What are properties?
      They are the characteristics of a substance
    • What do you call the Group 1 elements?
      Alkali metals
    • Why do elements in the same group have similar properties?
      Because they have the same number of electrons in the outer shell.
    • They have high densities and MP
      No, they have low density and MP.
    • Are the Group 1 elements reactive?
      Yes, they are very reactive
    • The reactivity decreases down the group.
      It increases.
    • Atoms get smaller down the group
      They get bigger.
    • Electrons get further away from the outer shell down the group.
      Correct
    • Does the attraction increase between the OS and nucleus?
      NO, it decreases.
    • The outer shell is removed more harder.
      It is removed easily.
    • Which type of solution do they produce when they react with water?
      Alkali solution
    • How does lithium react with water?
      > Slow reaction > Fizzing can be seen and heard
    • What can you observe when sodium reacts with water?
      > Large amounts of heat
    • How does potassium react with water?
      > Reacts violently > Burns with a lilac flame
    • Are the Group 1 elements hard to cut?
      They are soft and gets softer down the group.
