|
|
|
All the alkali metals are VERY reactive. why?
|
they have one electron in their outer shell that is able to form covelent or ionic bonds easily.
|
|
|
Name three properties that all Alkali Metals have?
|
they are very reactive.
they all create white compounds they all have one electron in the outer shell. they |
|
|
Is an alkali metal atom oxidised or reduced during a reaction?
|
It is oxidised.
|
|
|
why would an alkali metal seem dull in appearance?
|
It is very reactive so it has reacted to the water vapour (moisture) i the air and has developed an oxide layer on its surface.
|
|
|
Why do alkali metals float in water?
|
They have a lower density than water.
|
|
|
Why would you observe the floating alkali metal moving ontop of the water
|
The metal is reacting with the water to produce a metal hyroxide and hydrogen. This release of gas causes an effervesscence.
