    Sulfur Dioxide is slowly oxidised in the atmosphere to form sulfur trioxide

    I have to make a word + balanced equation for this
    I put
    SO2 + O2 -> SO3

    Element Y has 7 valence electrons. A full shell is 8 electrons. So Element Y needs 1 more electron to create a full valence shell.

    Element X has 3 valence electrons. This means it has a full valence beneath the outer shell, and then it has 3 extra electrons in its outer shell. It is most likely to donate 3 of its electrons to become stable.

    If Element Y needs 1 electron, three Y's will need 3 electrons. One X will provide 3 electrons necessary for the Ys. This is why the formula would be XY3.


    I'm pretty sure that's the correct explanation.

    Oh that makes sense!

    You must spread some Reputation around before giving it to Lavendrae again.
    UGH
    I'll rep you soon, I promise!

    Mind explaining why Ana's explanation isn't right, then? It was along my same train of thought

    [7:41:40 PM] Ana Banana:each element wants a full set of 8
    X is going to look for 1 more electron
    Y wants to give away it's extra 3 because it's easier to give away 3 than go looking for 5 more
    [7:41:46 PM] Ana Banana: Y is going to meet the first X, and give away one. That makes the X happy with a full set of 8, but Y still has two more extra ones.
    [7:42:18 PM | Edited 7:42:30 PM] Ana Banana: So it goes looking for 2 more Xs to give away the last two. In total it'll have met up with 3 different Xs
    [7:42:28 PM] ky: you need 3 xs to make the y completely stable
    [7:42:31 PM] ky: yeah haha

    What do you mean by 'make a word'?
    If your equation is SO2 + O2 -> SO3 then to balance it you'd just make it 2SO2 + O2 -> 2SO3
