Periodic Table
Transition metals
-
- hard & tough
- high density
- high melting point
-
-
-
-
-
Group VIII: Noble gases
-
-
-
- non metals
- colourless gases, occur naturally in air
- exists as single atoms, monatomic
- unreactive and inert
AS GOING DOWN THE GROUP
- density increase
- boiling point increase
Group I: Alkali Metals
-
-
-
- much softer (can be cut with a knife)
- lighter (low density)
- much lower melting and boiling points
- much more reactive
AS GOING DOWN THE GROUP
- softness increases
- density increases
- melting and boiling point decrease
Group VII: Halogens
-
-
-
- poisonous non metals
- exist as diatomic molecules (two atoms in each molecule)
- more reactive than most other non metals
AS GOING DOWN THE GROUP
- colour gets darker
- boiling pints increase
