Which number is the greater - the atoms making up the earth, or all potential questions and answers?
613412
Let S be the set of all atoms making up the earth. For each atom x belonging to S, ask the question "Where is x?". None of these questions is an actual question yet, but they are all potential questions. Since every atom must be somewhere each of these potential questions has a potential answer.\n\nIf, after that, there are any other questions at all, potential or otherwise, yours for instance, then the number of potential questions and answers must be larger than the number of atoms making up the earth.\n\nQED

"...the number of atoms in the observable universe can be estimated to be between 4×1078 and 6×1079. However, because of the possibly infinite nature of the universe, the total number of atoms in the entire universe may be much larger or even infinite."\n\nThis website for confirmation and more info --> http://www.biocrawler.com/encyclopedia/Atom

Most of the earth is made of iron and nickel.  This might not appear to be true at first because we see that the ground does not feel like metal, but the earth's inner and outer cores consist primarily of molten iron and nickel.  The earth's crust is only a few miles thick (at the thickest) and floats on top of the molten layers.

the atomic number is 5 b/c atomic number equals the number of elctrons and protons. You have 5 electrons so it should be 5.

What is the Earth made of?\nhttp://www.leo.lehigh.edu/envirosci/geology/penngeo/whatis/whatis.html\n\nChemical Structure of the Earth\nhttp://www.earth.northwestern.edu/people/seth/202/lectures/Minerals/compintro.htm\n\nStructure and composition of the Earth\nhttp://www.amonline.net.au/geoscience/earth/structure.htm\n\nThe way we know what makes the earth, chemically speaking is to test for it.  Such as the composition of the atmosphere is put through a mass spectrometer (http://answers.yahoo.com/question/index?qid=20060905084043AAQ20dx) this tells scientist exactly what elements are in the test sample and in what percent!  We do the same for tests in the earth, of course there are abundant other tests to perform, both chemical and by hand, to tell us a more rounded story of the formation of the earth's history.

It has been shown that there is an answer to the great question of life, the universe and everything. It was computed by Deep Thought, but really didn't seem to provide , well... an answer.\n\nThe great computer kindly pointed out that what the problem really was that no-one knew the question. Accordingly, the computer designed its successor, the Earth, to find the question to the ultimate answer.\n\nHowever, due to a slight Golgafrincham problem, and a small hooha with some Vogons the program went a bit wrong. The whole problem remains just as mysterious as it always has been, but a little more frustrating.

The greater the atomic number, the greater the number of protons in the nucleus, which USUALLY means a higher number of neutrons and electrons. The greater number of particles (protons, neutrons, and electrons) the greater the atomic radius. \n\nNote: There are different answers to this question depending upon what level of chemistry you are taking. But if you're taking a basic chemistry, it's the right answer.

Even though there are 92 elements that are naturally found, only eight of them are common in the rocks that make up the Earth’s outer layer, the crust. Together, these 8 elements make up more than 98% of the crust. \n\nThe 8 most common elements in Earth’s crust: \n46.6% Oxygen (O)\n27.7% Silica (Si)\n8.1% Aluminum (Al)\n5.0% Iron (Fe)\n3.6% Calcium (Ca)\n2.8% Sodium (Na)\n2.6% Potassium (K)\n2.1% Magnesium (Mg)\n\nThe picture on the left shows where these elements are located within the periodic table. Together, the elements oxygen and silica make up most of the Earth’s crust and these two elements are the ingredients for Earth’s most common mineral, quartz.

Iron. \n\nThat 46% figure for oxygen is not correct because it is only for the earth's crust. It does not include the mantle or the core. \n\nFor the entire planet iron makes up 35% of the mass of the planet and oxygen is only 30%. Silicon is 15%, magnesium 13%, and everything else is 7%. \n\nMy source is the USGS (which also cites the 46% oxygen for crust):\nhttp://pasadena.wr.usgs.gov/office/ganderson/es10/lectures/lecture04/lecture04.html

There are various means of determining this, and without any specific data on what elements are involved in the answer you are looking for, the link below is the best reference I can find that can answer this question in a mostly generalized way.

They're constantly adding new ones.  The new ones are synthetically created by bombarding already existing elements with neutrons.  Apparently, they're up to atomic no. 118, now:\n\nhttp://www.webelements.com/webelements/scholar/

I have disagree with the first answer as 35% of the earth is Iron. And while Aluminum is more abundent on the surface, nearly 80% of the core is iron. So I have to go with Iron.
