Many elements are found in nature in molecular form - two or more atoms (of the same type of element) are bonded together. Oxygen, for example, is most commonly found in its molecular form "O2" (two oxygen atoms chemically bonded together).
Elements are found on the periodic table.
"Organic" materials are defined as materials that contain the element carbon, but a broader interpretation will include all of the CHON elements; Carbon, Hydrogen, Oxygen, and Nitrogen. Any substance that contains all four elements is certainly an "organic" molecule, even if it formed in the absence of any life process.
No elements are found within other elements, which is how we define an element; As a substance consisting of one type of atom.
It depends on the type of meteorite: Stony meteorites are composed of Iron and Magnesium silicates. Stony-Iron meteorites are compose of silicates and Iron and Magnesium metals. Iron meteorites are primarily composed of Iron and Magnesium metals and Iron suphides.
Major elements that are found in cytoplasm are carbon, hydrogen, nitrogen and oxygen. The type of minerals present in the cytoplasm depends on cell type. Cells making up bones tend to have more minerals such as calcium in it.
Metals and non-metals
Transition metals
A meteoroid which reaches the ground is called a meteorite. A small number of meteorites have been found which scientists believe originated on the Moon or Mars. The composition of meteorites gives us valuable information about the universe. Meteorites typically fall into one of five categories.IronsThese meteorites are made of a crystalline iron-nickel alloy that resembles the outer core of the earth. Similar in structure to some asteroids (type M), 5.7% of meteorites are irons.Stony-IronsThese meteorites are mixtures of iron-nickel alloy and non-metallic mineral matter. Scientists believe they are like the material which would be found where the Earth's core meets the mantle. 1.5% of meteorite falls are stony irons.Stony MeteoritesThere are three subclasses of stony meteorites:Chondrites: These meteorites are the most numerous, comprising 85.7% of all meteorites found. They are characterized by chondrules: small (average diameter of 1 millimeter) spheres of formerly melted minerals that have melded with other minerals to form a solid rock. Chondrites are believed to be among the oldest rocks in the solar system and are similar in composition to the mantles and crusts of earth and the other terrestrial planets.Carbonaceous Chondrites: These meteorites are very rare and contain elemental carbon, the basic building block for life on earth.Achondrites: Stony meteorites without chondrules, representing about 7.1% of meteorites. Scientists believe that some of these meteorites originate on the surface of the Moon or Mars.From http://www.odec.ca/projects/2006/jauc6s2/kinds.htm

Sedimentary Rocks.
The ones that hit the earth are called meteorites.
The 10 most abundant elements in Mars crust (and atmosphere),determined from spacecraft analysis of the martian soil (andatmosphere) and analysis of meteorites believed to have originated onMars, (in order of abundance) are:O, OxygenSi, SiliconFe, IronMg, MagnesiumCa, CalciumS, SulfurAl, AluminumNa, SodiumK, PotassiumCl, Chlorine
