Silicon (a metalloid), Oxygen, Hydrogen, Phosphorus

Some people have limited their answer to the air on Earth, where indeed Nitrogen is the most abundant gas.\n\nHowever, the most abundant element in the Universe is Hydrogen, the simplest, with one proton and one electron.  Just remember that the Sun is mainly composed of Hydrogen, and the Sun is the biggest object in the Solar System.  There are millions of stars (like the sun) in the Milky Way and millions of galxies like the Milky Way.  Got the point?\n\nJust for a laugh, you may also ponder this quote: The two most abundant things in the universe are Hydrogen and stupidity. Harlan Ellison

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

Uranium is a naturally occurring element found in low levels within all rock, soil, and water. This is the highest-numbered element to be found naturally in significant quantities on earth.\n\nIt is considered to be more plentiful than antimony, beryllium, cadmium, gold, mercury, silver, or tungsten and is about as abundant as arsenic or molybdenum. It is found in many minerals including uraninite (also called pitchblende, most common uranium ore), autunite, uranophane, torbernite, and coffinite. Significant concentrations of uranium occur in some substances such as phosphate rock deposits, and minerals such as lignite, and monazite sands in uranium-rich ores (it is recovered commercially from these sources).\n\nUranium is found to some extent in the majority of rocks and sediments making up the Earth's crust, but is never found in concentrated deposits. \n\nThe most common uranium ore is pitchblende, which consists of a mixture of UO2 with U3O8. The largest known source of pitchblende is located in the Leopolville mines, in Congo, Africa. \n\nOther uranium containing minerals are euxenite, carnotite, brannerite and coffinite. The largest deposits of these ores are located in the USA, Canada, Russia and France.

The earth consists of 91 or 92 natural elements in many varied combinations. There is no one formula for the earth.

Lithosphere (most)\nHydrosphere\nBiosphere\nAtmosphere (least)\n\nwould be my guess

Compare the cosmic abundance of iron and nickle to the abundance of those elements in the crust.

woohoo geology... lets see if I remember anything...\n\nOkay here is a basic thing, the composition of rocks, especially it's silicate level, can tell us much about the molten/semimolten layers of Earth.... Okay I was enver very good in this subject, so look here...\nhttp://en.wikipedia.org/wiki/Geology

For common metals, iron is pretty much all you have.  Magnetite is an oxide of iron that is the about the most magnetic metal on earth.\n If you are looking for low weight, rare earth magnets are the way to go, but will cost you accordingly.  Neodymium or Samarium-Cobalt are your best bets there.

I say every single transitional metal is found on every single continent in the world in some quantity.  The most abundant T metal?  I'd say iron.

Probably copper, which was one of several elements known to prehistoric man, and can be found in free form.  Carbon, as charcoal, might also qualify.
