I thought it was really good. Plus, I didn't actually know that changing from solid to gas was called sublimation, so I've picked up a bit of info, thanks :)

I swear liquid atoms touch but gases dont....they slide over each other right? Good quiz as I now have to check my textbook!

no technically nothing touches as the electron atoms repel (but that's really Physics)

Because Hydrogen needs 3 moe oxygens so you add 2+1 Oxygens and there you have it!

It's a terrible quiz because the questions are very easy. I think that the quiz is for children. Still, I would do it if I could win a million euros. I don't think this web site is acceptable for clever people like me.

hydrogen is a diatomic molecule so as an element it has 2 electrons. liquid atoms sometimes touch and some of the questions are a bit confusing - but not too bad!

Hydrogen bonds in liquids are between two liquid atoms so wouldn't that be considered "touching"?

Qu 4, 7, 8 are too ambiguous

water is not called H20- it is the Formula and hydrogen does not fill oxygen- it is the electrons that 'fill' but not scientific

on ion is not a charged ATom, an ion is never an atom- an ion is a charged species formed when an atom gains or loses electrons

liquid atoms touch or define touch - interact repel bounce off each other etc- just not in fixed positions-

Sarah Aspland

Report Sat 30th April, 2011 @ 14:56

liquid atoms sometimes touch, and sometimes don't, theyre not like gases that float around everywhere, but are less ordered and fixed than solids, therefore that question is slightly ambigous!

Well for starters Hydrogen atoms are just Protons - they don't have electrons so Q3. is wrong.
And Liquid particles can touch so Q7 is also wrong

Yeah some of the answers are wrong and ambiguous. For example Hydrogen is electron-deficient in some senses. Also a covalent bond? you didn't specify which one, dative-covalent or...? Oh finally the water question, because you need two hydrogen atoms to fill up 1 oxygen. That's wrong. As water is a non-linear molecule with two bonding pairs of electrons and two lone pairs of electrons and as lone pairs of electrons repel each other more than bonding pairs it forms a bent molecule with bond angles of 104.5degrees. Therefore as it has two lone pairs of electrons it doesn't necessarily mean two hydrogen atoms 'fill' it up. Thanks anyway, hope this helps :)
