THe elements

Haha
Water is a compound of hydrogen and oxygen.
Mostly iron, it considered to be the planet with the most rich iron. There is also some hydrogen, oxygen, and helium
which of these elements must be in organic compuonds oxygen hydrogen carbon helium or iron
A quark :) An element such as gold, silver, iron, oxygen, hydrogen, helium
hydrogen (75%) and helium (25%), roughly yes, but to be more precise: The sun consists of 71 % Hydrogen, 27 % Helium, 1 % Oxygen and the last percent is made of Carbon, Nitrogen, Silicon, Magnesium, Neon, Iron and Sulfur.
Eath

Theres iron in the core so there is a lot of iron. It also has hydrogen, oxygen helium and a little magnesium.
Earth
hydrogen fusing to make helium The sun is made completely of a mixture of 75% hydrogen 25% helium. 74% hydrogen, 24% helium, iron, nickel, oxygen, silicon, sulfur, magnesium, carbon, neon, calcium, chromium, and 1% oxygen.

No. Both are elements. Helium is a noble gas and iron is a transition metal.
No. Its a heap of gases such as Hydrogen, Helium, Iron, Nickel, Oxygen, Silicon, Sulfur, Magneseum, Carbon, Neon, Calcium, and Chromium.
Of the listed items, water and carbon dioxide are compounds, not elements. The others (mercury, iron, helium, oxygen, carbon, and bromine) all have more than one isotope. So none of the listed materials have "one type of atom."
