|
What is an Alkali Metal?
|
It is a metal that has only one electron in their valance orbital, so they always become +1 compounds.
|
|
|
What happens to the atom as you go down the group?
|
The atomic radii increases therefore the energy needed to remove the valance electron becomes less. This results to the reactivity to increase.
