- We use Evaporation when we want to remove liquid from a mixture of Liquid and dissolved solids
- Filtration
- We use this when we want to separate particles from a solid
- Transition Element
- Between group 2 and 3
- They have a higher melting point
- they are a good conduct of heat and electricity
- They are less reactive than group 1 metals
- Reaction
- Group 1 metals react readily with oxygen at room temp but transition metals react with oxygen either very slowly or not at all
- Transition metals do not react with water, unlike the alkali metals which vigorously with water
- Transition metals form positive ions like all metals, However each transition metals can form positive ions with different charges
- In transition metal compounds we use roman numerals to show the charge
- Element
