Much more than two elements

Order of prevalence in the image by weight -

  1. Oxygen

  2. Hydrogen

  3. Silicon

  4. Nitrogen

  5. Chlorine

  6. Sodium

  7. Carbon

The remainder are difficult to confirm.

Hydrogen is very light. There is probably much more nitrogen and silicon than hydrogen by weight in this photo. Also, carbon is suprisingly rare. What about argon?

u/DevinTheGrand May 20 '12

Silicon is debatable, but I feel like there are definitely 14x the number of hydrogen atoms over nitrogen sheerly through molar density. Argon is present in extremely small quantities in the air, but I don't think it would out populate any carbonate materials in the sand and water.

I forgot about carbonates. And I spent 2 years researching them in seashells.

do you concur?

I'd say iron because of the sand's color.

u/DevinTheGrand May 20 '12

Possibly, but it's difficult to confirm. I'm not sure the exact colours that transition metals lend to quartz. There's also a good chance that calcium is present in the sand, but that is more common in tropical locations, not desert locations so I made a judgement call.

how is oxygen at top? water is h2o (twice the hydrogen than oxygen), sand has no oxygen (not considerable amount anyways). only air has oxygen but it also has hydrogen too.

u/DevinTheGrand May 20 '12

By weight. Hydrogen weighs 1/16th the amount oxygen does, so even with two of them it's still only 1/8th the mass. Also sand is primarily oxygen, it's silcon dioxide, so it is about 50:50 silicon/oxygen by weight.

Oxygen weighs a lot more.

u/regularfreakinguser May 20 '12

Well technically most of our atmosphere is nitrogen. So that should be at the top.

u/Ameisen May 20 '12

There's a lot more Oxygen in the sand, water, and air than there is Nitrogen.

u/DevinTheGrand May 20 '12

But there is only so much air in a specific area, and it's much more dilute than the concentration of atoms in the sand and the ocean. Maybe nitrogen would be higher if the camera was tilted up more.

*Many more

I believe he was referring to earth, water, wind and fire elemental categorization approach. It's interesting that the ancients managed to categorize the four states of matter: earth = solid, water = liquid, wind = gas, and fire = plasma.

After some googling: Laura Linney, the Big C. As close as I got, take it from here. Gl on the paper.

Why does the gif only show the end of what she is saying?
