Anyone know of a website that has a list of elements that can tell me if element (1) is mixed with element (2) you get element (1+2) and info like the new atomic number, weight, etc..

Not entirely sure what you mean.

Here's a periodic table.

If you mix hydrogen (element 1) with helium (element 2) you get a gas mixture of the two gases. They do not react. If you mix hydrogen (e1(i1)) with oxygen (e8(i16,i17,i18)), some water will form. Where e = element and i = isotope
If you bombard hydrogen atoms together at high temperatures (about 50 million C), you will create helium (i3 and i4).

There are many isotopes of each element. I think tin (Zn, e50) has the most stable isotopes at 10. Here's a pic of the first 28 elements and their isotopes. 0 at the bottom is a neutron. The white squares are what you would find on the periodic table. The black squares are stable isotopes. H1 is regular hydrogen with 1 proton and no neutrons. H2 is duterium hydrogen with a neutron. H3 is tritium hydrogen with 2 neutrons, used in H bombs and is unstable with a 12.33 year half life.

Does this help?

And this is where they're at for creating new, heavy elements.

Sorry Snowcrash I was never good at explaining things clearly.
Thanks for your wisdom.

I'm just looking for a list of most common mixes, like your example of hydrogen+helium.
I best describe things by example so I will try and give a better example.

Lutetium + Oxegen
4Lu + 302 = ZLu203
End Poduct: lutetium {11}Oxide

If I can find a page that has a list laid out similar to my example I would be able to add some great info to a Flash 3D interactive periodic Table project.

Ahh, you mean creation of compounds. As far as I know there are millions of these. And that's just the ones using carbon.

Most compounds are created via a reaction. CH4 + O2 + heat = C + 2H2O

Or methane + molecular oxygen + a flame =  soot + water

The elements one side balance on the other. What reacts with what is due to the electron shell theory and is what the periodic table is based on.

The electons in a neutral atom/element are equal to it's protons. C = 6, H = 1, O = 8.
The electron shells go 2-8-8-18-18-32 (elements 2,10,18,36,54,86 are the noble gases)
Hydrogen has 1 electron but likes 2 for the first shell. Molecular hydrogen is H2 due to this.
Carbon has 2 electrons in the inner shell and 4 in the next shell that likes 8. So it is happy with 4 hydrogens.
Oxygen is weird. It has 6 electron in it's outer shell but also likes 8. So H2O in neutral and stable but O2 is +4 (4 less electrons than it likes) and is very reactive. It also comes in O3 (Ozone)

Just your basic carbohydrates hydrocarbons are CH4 (methane), C2H6 (ethane) C3H8 (propane), C4H10 (butane), C8H18 (octane)

To complicate this further, there are 3 types of electron bond. Valent, covalent and van de waals, I think.

Thanks Snowcrash   , compounds was the word I was looking for, that I could not remember. I use to know a lot about elements and creating compounds back in high school days, Though not using the Table of elements since then, most of the input got lost, hidden or overwritten   If you don't use it you loose it, one wise person once said.


EDIT: I found this site which suits my needs Thanks again Snowcrash

Except that those are actually hydrocarbons. Carbohydrates are sugars, such as sucrose (C₁₂H₂₂O₁₁), glucose (C₆H₁₂O₆), fructose (C₆H₁₂O₆ - but with a different lattice arrangement), lactose (same as sucrose, but again with a different lattice arrangement), etc. The difference is that hydrocarbons have little to no oxygen in the chemical lattice, whereas carbohydrates do.

By the way, I've done some poking around the site I linked. It's got some REALLY fascinating stuff! I'm glad Google brought it to my attention.

Thought about this one too. Add an extra oxygen molecule and it burns better.

CH4 + 2O2 + heat = CO2 + 2H2O

Or methane + molecular oxygen + a flame =  carbon dioxide + water

You've missed off pectin (used in making (EN)jam/(USA)jelly)  C₆H₁₀O₇ a mono saccharide and all the polysaccharides.
Oops, I appear to have disappeared up my... 

No more so than I did, Snowy. Sometimes I get all carried away. Sorry.
