17
Q

What are alkalis stored in and why

A

Oil to stop them reacting with the water in air

18
Q

Size of alkali metal pattern

A

Increase downward

19
Q

Colour of chlorine

A

Green yellow gas

20
Q

Colour of bromine

A

Red brown liquid

21
Q

Iodine

A

Grey/black solid

22
Q

A halogen and a metal

A

Forms an ionic salt

23
Q

Lithium and water

A

Moves around surface
Hisses
Produces has bubbles
Gets smaller and disappears

24
Q

Experiments to find reactivity

A

Mix chlorine bromine or iodine will halide solution
The solution will turn to the colour of the more reactive elements
These are redox reactions

25
Q

Sodium and water

A 
Moves around surface 
Hisses 
Produces gas bubbles 
Melts into a shiny ball
Gets smaller then disappears
26
Q

Potassium and water

A 
Moves around surface
Hisses 
Produces gas bubbles 
Melts into shiny ball 
Burns lilac
Gets smaller and disappears
