only the most unreactive elements (such as what?) occur as what? | Only the most unreactive metals, such as silver and gold, occur as elements in their ores. |
the rest of the metals are found as what? | compounds, therefore they have to be extracted |
the method of extraction is linked to what? | the position of the metal in the reactivity series |
The more reactive metals are what and why? | harder to extract as they are better at 'keeping hold' of the elements in their compound |
reactivity series acronym: | Please stop lovely calling my aunt carol zelda cause she's gone |
elements above carbon in the reactivity series have to be extracted using: | electrolysis |
elements below carbon in the reactivity series have be extracted using: | the blast the furnace |
silver and gold extration: | don't!! because they are found as pure elements |
