Group 1 And 7 Flashcards
1
Q
Group 1
A
ALKALI METALS
- one electron in outermost shell
- low melting and boiling points that DECREASE DOWN the group
- MORE REACTIVE DOWN THE GROUP
2
Q
Where are alkali metals stored ?
A
Under ooo because they react with oxygen and water
3
Q
Group 1 metals have a low ?
A
DENSITY
-Lithium, potassium and sodium are less dense than water so they float
4
Q
What happens when a metal dissolves in water ?
A
Alkaline solution is produced
5
Q
Group 7
A
HALOGENS
- reactivity decreases down the group
- produce ionic salts when reacting with metals
