    It's not GCSE. I think it is touched on at the end of A2 physics, but I'm not sure.

    It is interesting though.
    I am planing to do physics at A-Levels so I will learn about it and enjoy it cuz I love science
    R u doing A-Levels right now?

    Yeah, you asked me on your A-level choices thread.

    An atom/molecule with greater bonds but the same particles will have less mass.
    I don't get this sorry

    There is alot...
    Electrolysis
    Everything about Electrolysis I don't understand, the cathode and anode stuff. I know that they're postitive and negative but its just which atoms will be positive. The stuff formed in electrolysis, how do you work out what will be formed.
    Thanks!! I really struggle with Chemistry even with revision guides. My parents are buying me mygcsescience though

    Anion-negative
    Anode-positive
    Cation-positive
    Cathode-negative

    The ions move to the oppositely charged(similarly named) electrode.

    You should normally have equations to remember rather than rules, but generally any atom/group will take its usual ionic charge.(eg Cl-, Na+, H+, O2-)

    So it's electrolysis... so we r gonna do electrolysis of Aluminumoxide. All it happens in electrolysis is ions changing to atom So basically Al is metal so it losses 3 electrons to become Al3+ so it goes to cathode (Negative) and gain 3 electrons to become Al. On the other end O loses gain 2 electron to become O2- so it goes to anode (Positive) to lose 2 electrons to become O. This happens when the Aluminumoxide is molten .

    Fallen99 will be able to help you with that. I did GCSE a few years ago so can't really remember the questions.

    Do you have any common GCSE questions you can ask me on electrolysis?

    Descibe and expalin how electrolysis is used to obtain pure copper from a lump of impure copper??
    Good Luck
