Cos i am totally lost !!! xxxx

This website seems to explain ionic bonding and [[ ebn=&ebs=&ebl=&elc= covalent bonding] OK.

Basically, ionic bonding is where one atome loses the electron, and the other gets it.

And covalent bonding is where they both share an electron.

DS has been doing this recently!

Ooh, lets try that again!

covalent bonding

Have you looked at BBC Bitesize?

Hi Have looked at bbc bitesize yes thanks.
Muminscotland that link was fabulous thanks.

DD is stuck on a couple of questions -
What type of bonding would an organic compound have ?

Suggest a simple test that would determine whether white crystals were salt or crystals of an organic compound.

In what ways would the results of this test be differrent for the 2 differrent compounds?

Explain your reasons for the difference you have stated in last question using your knowledge of the structure of ionic and covalent compounds.

Any help would be really appreciated because i am trying to help dd and we are both too tired too sit down and start from the beginning like we usually do because she`s just come home from completing her Duke of Ed expedition and i`ve slipped a disk in my neck fgs !
I wouldn`t normally ask but any help would be very very welcome x

A covalent bond shares electrons. An ionic bond is formed due to the attraction of opposite charges - does that help>?

Covalent bonds are usually much stronger. I think most organic compounds have covalent bonding

Fab thanks .Yes thats def 1 down.

Organic compounds have covalent bonds.

To look at the next question your dc has to look at the note to check the properties of ionic and covalent compunds (I bet these are in his notes/text book), they will behave differently.

This will allow him to work out a test between the two.

the reason that they behave differently is that ionic compunds can be charged in a way that covalent ones can't (they can have separation of charge, to a degree, but not at GCSE level smile)

A organic compound would have covalent bonding, because it would be non-metallic elements.
I've no idea how you would test for it!

I know the answer to the second quiestion, but I'm doing that really irritation thing that teachers do, when they ttry to get the kids to work it out for themselves! wink

If he doesn't have a table that compares them have a shuft at this

HINT, the last of the 4 points is the one I think they cant him to talk about, but let him look it up first smile
