Groups Periodic Table Flashcards
1
Q
Alkali Metals
A
- Forms ions with a charge of +1.
- Extreme chemical behaviour and far too reactive to be found naturally.
2
Q
Alkaline Earths
A
- Act similar but less reactive than alkali metals.
- Forms ions with a charge of +2.
3
Q
Halogens
A
- Forms ions with a charge of -1.
- Not found in nature, but are found in various types of salts.
- Coloured and poisonous vapours.
- Less reactive down the group.
4
Q
Noble Gases
A
- Known as inert gases.
- Incredibly stable and react only under rare or extreme circumstances.
- Density increases down the group.
5
Q
Transition Elements
A
- Metals with similar properties.
- Relatively hard with high melting points.
6
Q
Lanthanides
A
- Reactive silver metals.
- ‘Rare-earth metals’.
7
Q
Actinides
A
- Radioactive and release energy upon radioactive decay.
