A great deal of the sun is hydrogen (about 75% I think), and most of the remaining portion is composed of helium.

Yay piggies. And actually ignore the bonus point thingy. Well yes it's mostly comprised of Zinc Sulphide but that's not all it is. So there isn't really a chemical name or formula for sphalerite. Anyway...Answer: SPHALERITE.Well Done 2bigpigs. That's 2 points. Oh and I'll give you the bonus point anyway since Zinc Sulphide was initially what I was thinking of when I first put down the bonus question. 3 points in total.Any newcomers are welcome to join.

I know nothing about that but I think the most abundant metal in Earth's crust is iron.NO.... wait, actually it's silicon... or is that a metalloid?Silicon is a metalloid. Aluminum is my final answer.

Glucose is C6H12O6, so the three elements found in it are Carbon, Hydrogen, and Oxygen.

Actually what teds said is glucose,Lactose or fructose.He is right.You see there are many such ones with the same formula.And there are many for the on you gave too.C6h12O6 is a monosacharide and C12H22O11 ike so is Dissacharide Eg maltose,Lactose.Since glucose is simple it is a monosaccharide and the Disacharides aren't soluble in water..

Oxygen? Is that supposed to be funny? Since when was oxygen a metal? lol. Well, I'm assuming you misread the question. Anyway...

Oh metal,Same case as the tea jamzemu,My bad.Hey you said 2 pts and gave him only one.You also said congrats teds and gave me pts,But i had gotten the answer right anyway.

Yup it is what 2bigpigs said. And it could also be written the way undefinable mentioned.Answer: 1s2,2s2,2p6,3s2,3p6,4s1Well Done teds. That's 2 points. Any newcomers are welcome to join.
