1
Radium is a RADIOACTIVE element which used to be used to make glow in the dark paint.
2
The reactivity of the group 2 metals increases down the group as the outer ELECTRONS get further from the nucleus and become easier to remove.
3
Group 2 metals react with HALOGENS to form metal halides
4
The alkaline earth metal react with water to form metal hydroxides except for Be which has a protective oxide layer preventing REACTION.
5
They are less REACTIVE than group 1.
6
The group 2 elements are shiny, silvery-white, and somewhat reactive METALS, some of which occur naturally as free elements.
7
Group 2 metals react with OXYGEN to form metal oxides.
8
The GROUP 2 elements are shiny, silvery-white, and somewhat reactive metals, some of which occur naturally as free elements.
9
The reactivity of the group 2 metals increases down the group as the outer electrons get further from the NUCLEUS and become easier to remove.
