Which of the elements is not one of the ten most abundant in Earth's crust, oceans, and atmosphere? Best Answer: Carbon. Although carbon is found in lifeforms and many minerals like calcite or aragonite, it is not all that common in the big picture. You have to remember just how small all of us living things are on the surface with respect to even the crust which is still just a sliver of the earth. Those are all among the top 10 elements. http://en.wikipedia.org/wiki/Abundance_o...

- The densest naturally occurring element on the planet is osmium, a metal in the platinum family with a density of 22.6 grams per cubic centimeter. If that means nothing to you, then you’re normal. By comparison, lead is 11.3 grams per cm cubed.

What is the most abundant element on Earth AND in the human body? Answer: The most abundant element in the universe is hydrogen, which makes up about 3/4 of all matter! Helium makes up most of the remaining 25%. Oxygen is the third most abundant element in the universe. All of the other elements are relatively rare. The chemical composition of the earth is quite a bit different from that of the universe. The most abundant element in the earth's crust is oxygen, making up 46.6% of the earth's mass. Silicon is the second most abundant element (27.7%), followed by aluminum (8.1%), iron (5.0%), calcium (3.6%), sodium (2.8%), potassium (2.6%). and magnesium (2.1%). These eight elements account for approximately 98.5% of the total mass of the earth's crust.

What is most common material on earth? Silicon and oxygen. The second most common is iron. Hope this helps. Measured by mass, silicon makes up 25.7% of the Earth's crust and is the second most abundant element on Earth, after oxygen.. I was taught silican at college. I think anyway. water. it makes up 60% of earths surface. but the isnide of earth is dirt and lava. so probably one of those 3.

REE - Rare Earth Elements and their Uses The rare earth elements are all metals, and the group is often referred to as the rare earth metals.. These metals have many similar properties and that often causes them to be found together in geologic deposits.are earth elements are not as rare as their name implies. Thulium and lutetium are the two least abundant rare earth elements-but they each have an average crustal abundance that is nearly 200 times greater than the crustal abundance of gold (1).

How many naturally occuring chemical elements are there on Earth? Both neptunium and plutonium can be detected in uranium minerals, though the amounts are small. Uranium minerals regularly contain 1.8 microgrammes of neptunium and up to 0.15 microgrammes of plutonium per ton uranium. In addition there is also primeval plutonium on Earth. The isotope 244 has a half-life of 82.6 million years, and this is enough that a minute amount has survived since the elements making up the Earth were created in the last supernova event before the birth of the solar system.

Potassium It is found dissolved in sea water (which is 0.04% potassium by weight), and is part of many minerals. Naturally occurring potassium is composed of three isotopes, one of which, 40K, is radioactive. Traces of 40K are found in all potassium, and it is the most common radioisotope in the human body.

- The rarest elements in the crust (shown in yellow) are not the heaviest, but are rather the siderophile (iron-loving) elements in the Goldschmidt classification of elements. These have been depleted by being relocated deeper into the Earth's core. Their abundance in meteoroids is higher.

Rare-earth element However, because of their geochemical properties, rare earth elements are typically dispersed and not often found concentrated as rare earth minerals in economically exploitable ore deposits. It was the very scarcity of these minerals (previously called earths) that led to the term rare earth.are earth cerium is actually the 25th most abundant element in Earth's crust, having 68 parts per million (about as common as copper). Only the highly unstable and radioactive promethium rare earth is quite scarce. The rare earth elements are often found together.

Chemical element Iron is the most abundant element (by mass) making up the Earth, while oxygen is the most common element in the crust of the earth. Chemical elements constitute approximately 15% of the matter in the universe: the remainder is dark matter, the composition of it is unknown, but it is not composed of chemical elements.s a special case, the three naturally occurring isotopes of the element hydrogen are often specified as H for 1 H (protium), D for 2 H (deuterium), and T for 3 H (tritium). This convention is easier to use in chemical equations, replacing the need to write out the mass number for each atom.
