Groups In The Periodic Table / Flashcards
1
Q
Group 1
A
Group 1 metals are known as the ‘Alkali Metals’
2
Q
Physical properties of group 1 metals
A
- Low melting and boiling points
* Very soft
3
Q
Alkali metals form…
A
Ionic compounds. They loose their single outer electron.
• They form 1+ ions.
4
Q
Group 7
A
Group 7 elements are known as the ‘Halogens’
5
Q
Properties of Group 7 elements
A
As you go down group 7, the melting points and boiling pints of the halogens increase.
6
Q
Reactivity of Group 7 elements
A
As you go down group 7 reactivity decreases
7
Q
Test for chlorine
A
Damp blue litmus paper turns red then white
8
Q
Group 0
A
Group 0 elements are known as ‘Noble Gases’
9
Q
Properties of noble gases
A
- Inert - they don’t react with much at all, the reasons for this is that they have a full outer shell of electrons.
- Colourless gases
- Non-flammable
10
Q
Boiling and melting pints of noble gases
A
Boiling point and melting point increase as you go down group 0
