Hi i'm having a hard time trying to put into words why H2 has the melting it has and its solubility in h20. I'd greatly appreciate it if someone could put into words why it has those specific properties.

Have you looked at wikipedia and searched using GOOGLE to help your understanding the properties of water and hydrogen?
 I am interested in why you chose solubility of hydrogen in water as one of the discussion points.

Sorry, must have skipped over that rule
I'm assuming that due to its low amount of electrons and its non-polarity that the intermolcular bonds it makes through Dispersion forces are short and weak owing to its low melting point but that all i got for melting point. For solubility in H20, i know due to its non-polarity it won't dissolve as fast as a polar solution but im still not sure why it would be lower than other gases

Any takers? There's not much good information online

I can't give an authoritative answer but these are some points I would consider:

1) how readily can the permanent dipole in the water molecules induce a dipole in the hydrogen molecules?

2) when comparing the solubility of hydrogen to other gases, to what extent does the solubility of those gases reflect their tendency to react with water? Eg: CO2 will become H2CO3, NH3 will become NH4, Cl2 will become HCl and HOCl.

3) Considering qu 2, how feasible is it that H2 could react with water?

That's disappointing to hear, because our rules state that you're supposed to make an attempt, and while not Googling is a lack of work, a quick Google shouldn't be all the work you attempt.

Sometimes we ask people to check their class notes, or textbook.  But maybe we should take a different tack, in your case.

What melting point should hydrogen have, do you think?  What's odd about its melting point?  I'm really asking you, because I don't know the answer.  Or rather, why its a question at all.  Compare with some other gasses, is its melting point higher, or lower than it some others?  And why do you think that's the case.  You've done some good work here.

'm assuming that due to its low amount of electrons and its non-polarity that the intermolcular bonds it makes through Dispersion forces are short and weak owing to its low melting point but that all i got for melting point.

But it looks like you're just throwing buzzwords out there.  Maybe if you compare it do some other gasses, or use the definition of melting point with regard to intermolecular forces, you'll have a definition you can be proud of (and useful on an exam question.)

I get what you're saying but i need to sum the melting point up in a few sentences and relate it back  to bonding. Also, analyzing the melting point of other gases all relate back to the number of electrons which in turn relates back to inter molecular attractions
