Q

What was absent from mendeleeves table and why

A

The noble gases were absent, as they were u discovered becuase they are invisible and totally un reactive

23
Q

What was separated in the modern periodic table

A

The transition metals now form a separate block

24
Q

Is there gaps in the modern periodic table

A

No

25
Q

3 groups

A
  • alkali metals
  • halogens
  • noble gases
26
Q

What are alkali metals stored under and why

A

Oil, to stop it reacting with oxygen and water vapour

27
Q

Why does reactivity increase downwards for alkali metals

A

The outer shell electron becomes further from the nucleus, there fore there is less attraction, so the electron is lost faster

28
Q

Why do alkali metals have similar properties

A

They are all trying to lose 1 electron

29
Q

Metal + water makes …..

A

Metal hydroxide + hydrogen

30
Q

Observations for lithium reaction (6)

A
  • fizzes as bubbles of gas produced
  • floats
  • moves on surface
  • heat produced
  • metal disappears
  • colourless solution formed
31
Q

Observations for sodium reaction (7)

A
  • fizzes as bubbles of gas produced
  • floats
  • moves on surface
  • heat produced
  • metal disappears
  • colourless solution formed
  • silver ball formed
32
Q

Observations for potassium reaction (8)

A
  • burns with lilac flame
  • crackle at the end
  • fizzes as bubbles of gas produced
  • floats
  • moves around
  • heat produced
  • metal disappears
  • colourless solution is formed
33
Q

Why is rubidium and caesium to dangerous to show

A

They have explosive reactions

34
Q

Equation for lithium reaction

A

2li + 2H20 makes 2LiOH + H2

35
Q

Equation for sodium reaction

A

2Na + 2H2O makes 2NaOH + H2

36
Q

Equation for potassium reaction

A

2K + 2H20 makes 2KOH + H2

37
Q

Which alkali metal forms an ion fastest

A

Francium

38
Q

Gas elements in the halogens

A

Chlorine

Fluorine

39
Q

Liquid of the halogens

A

Bromine

40
Q

Solids of the halogens

A

Iodine

Astatine

41
Q

How reactive is fluorine compared to astatine and why

A

Fluorine is much more reactive, this is because the the halogens are trying to gain 1 electron and because astatine’s outer shell is much further from the nucleus is is much harder for it to gain 1 extra electron

42
Q

What happens when iodine sublimes

A

A purple vapour is released

43
Q

Test for chlorine gas and the result

A

Damp universal indicator paper changes to red then bleaches white

44
Q

Colour of fluorine

A

Yellow

45
Q

Colour of chlorine

A

46
Q

Colour of bromine

A

Red-brown

47
Q

Colour of iodine

A

Grey-black

48
Q

Colour of astatine

A

Black

49
Q

Why do the halogens have similar properties

A

They are all trying to gain 1 electron

50
Q

Properties of the noble gases (3)

A
  • colourless
  • un reactive
  • all have full outer shells
51
Q

A
  • copper
  • iron
  • silver
52
Q

Properties of the transition metals (3)

A
