1a. The carboneasiestelectricityfurnacegoldhigherironjewelleryleadlesslowermeltingmoreoilreactivesmeltingsodiumsofttechnologyunreactiveuses the metal in the reactivity series, the carboneasiestelectricityfurnacegoldhigherironjewelleryleadlesslowermeltingmoreoilreactivesmeltingsodiumsofttechnologyunreactiveuses difficult it is to extract from its compounds.
1b. Metals carboneasiestelectricityfurnacegoldhigherironjewelleryleadlesslowermeltingmoreoilreactivesmeltingsodiumsofttechnologyunreactiveuses in the reactivity series are carboneasiestelectricityfurnacegoldhigherironjewelleryleadlesslowermeltingmoreoilreactivesmeltingsodiumsofttechnologyunreactiveuses difficult to extract.

2a. Many of the less reactive metals can be extracted by heating an oxide ore with carboneasiestelectricityfurnacegoldhigherironjewelleryleadlesslowermeltingmoreoilreactivesmeltingsodiumsofttechnologyunreactiveuses (charcoal, graphite), in a a process called carboneasiestelectricityfurnacegoldhigherironjewelleryleadlesslowermeltingmoreoilreactivesmeltingsodiumsofttechnologyunreactiveuses.
2b. The metal carboneasiestelectricityfurnacegoldhigherironjewelleryleadlesslowermeltingmoreoilreactivesmeltingsodiumsofttechnologyunreactiveuses can be obtained in this way in a blast carboneasiestelectricityfurnacegoldhigherironjewelleryleadlesslowermeltingmoreoilreactivesmeltingsodiumsofttechnologyunreactiveuses (picture above).

3. Other more reactive metals are obtained by carboneasiestelectricityfurnacegoldhigherironjewelleryleadlesslowermeltingmoreoilreactivesmeltingsodiumsofttechnologyunreactiveuses one of its compounds to free the particles and then passing carboneasiestelectricityfurnacegoldhigherironjewelleryleadlesslowermeltingmoreoilreactivesmeltingsodiumsofttechnologyunreactiveuses through the melt. This process is called electrolysis and it is how we make carboneasiestelectricityfurnacegoldhigherironjewelleryleadlesslowermeltingmoreoilreactivesmeltingsodiumsofttechnologyunreactiveuses or aluminium.

4a. The metals which are carboneasiestelectricityfurnacegoldhigherironjewelleryleadlesslowermeltingmoreoilreactivesmeltingsodiumsofttechnologyunreactiveuses to extract have been used for thousands of years, but metals like aluminium were not extracted until recently when more advanced carboneasiestelectricityfurnacegoldhigherironjewelleryleadlesslowermeltingmoreoilreactivesmeltingsodiumsofttechnologyunreactiveuses was invented.

5a. The reactivity of a metal explains some of its carboneasiestelectricityfurnacegoldhigherironjewelleryleadlesslowermeltingmoreoilreactivesmeltingsodiumsofttechnologyunreactiveuses.
5b. the precious metal carboneasiestelectricityfurnacegoldhigherironjewelleryleadlesslowermeltingmoreoilreactivesmeltingsodiumsofttechnologyunreactiveuses is so carboneasiestelectricityfurnacegoldhigherironjewelleryleadlesslowermeltingmoreoilreactivesmeltingsodiumsofttechnologyunreactiveuses it has been used for carboneasiestelectricityfurnacegoldhigherironjewelleryleadlesslowermeltingmoreoilreactivesmeltingsodiumsofttechnologyunreactiveuses for thousands of years and shining .
5c. Metals such as carboneasiestelectricityfurnacegoldhigherironjewelleryleadlesslowermeltingmoreoilreactivesmeltingsodiumsofttechnologyunreactiveuses or copper can used in roofing because they are relatively carboneasiestelectricityfurnacegoldhigherironjewelleryleadlesslowermeltingmoreoilreactivesmeltingsodiumsofttechnologyunreactiveuses.
5d. Sodium is so carboneasiestelectricityfurnacegoldhigherironjewelleryleadlesslowermeltingmoreoilreactivesmeltingsodiumsofttechnologyunreactiveuses with oxygen or water, it is kept under carboneasiestelectricityfurnacegoldhigherironjewelleryleadlesslowermeltingmoreoilreactivesmeltingsodiumsofttechnologyunreactiveuses and cannot be used for any outdoor purpose and not much else, since it is so carboneasiestelectricityfurnacegoldhigherironjewelleryleadlesslowermeltingmoreoilreactivesmeltingsodiumsofttechnologyunreactiveuses!
