What is electrolysis used for (in industrial terms)?
To separate any metals higher that carbon in the reactivity series from their ores.
1 of 6
Describe covalent bonding, naming an example.
Covalent bonding is where atoms which both need to gain or lose electrons share their electrons in order to gain a full outer shell. An example of this is two hydrogen atoms.
2 of 6
Name a giant structure and give one use of it.
Diamond is used in jewlery.
