What chemical element is the human body mostly comprised of?  Tell me how you got your answer?

The answer depends on whether you are asking for the largest contributor to the mass of the human body or the largest contributor in number of atoms to the human body.  It is common knowledge that humans are mostly composed of water (estimates may range from 70% to 80% by mass).  Since most of the mass of water (H2O)is due to the oxygen rather than the hydrogen (a ratio of about 8 lb of oxygen to every 1 lb of hydrogen) then most of the body's mass comes from oxygen.\nOf course oxygen is found in almost every other molecule in our body as well, as is hydrogen which brings us to the second possible answer.  Since there are two hydrogen atoms for every oxygen atom in water then water has twice as many hydrogen atoms as it does oxygen atoms.  It is true that we also have lots of carbon based molecules.  They are carbon based because carbon forms the main chain of the molecule, but almost every carbon in our body has a few hydrogen atoms hanging off of it.  The average is about two hydrogen atoms for every one carbon atom.  Therefore, hydrogen is by far the most abundant element in number.

Here is an interesting fact.  The interior of our bones are lined with copper atoms.\nResearch it, its true.

Yes it's the same element,except that in the human body it's an ionized form,not a metallic form, only traces are required or else it would cause severe poisoning causing CNS and liver malfunction.

Amino acids.\n\nOH, I thought you asked what they are made OF. Sorry - Ribosomes!

There are traditionally only 4 elements - Fire, Water, Earth and Air / Wind. These were believed by the ancient greeks to be the fundemental basis of life. \n\nScientifically, there are not only several elements needed for life to exist but also certain conditions of environment also - the best elemental mix would struggle to form life in the near vacuum of space.\n\nAll known life is carbon based. The other elements needed (depending on environment) would include hydrogen, oxygen, and nitrogen.\n\nIf you are talking about throretical extra terrestrial life, this could be silicon based and have an entirely different chemistry to anything we would recognise.

Everything around us is a chemical. That is all foods, all fibers, natural materials in the environment as well as the man made materials.

Protons, neutrons, and electrons.

No, the human body is a very large collection of atoms, the cells are made up of all sorts of things taht each could be divided into smaller things and that on the other hand maybe can bedivided into smaller things until you find that all that is left is atoms.

1) is false, all the elements in living things can be found in non-living things\n\n2) this more tricky, what are these 4 elements most common in plants? I'm guessing: Hydrogen and Oxygen, (from water) Carbon, and . . .nitrogen???\nall these can be found in animals\nare you sure the question is asking about elements? elements in living things are pretty common to another. Its the compounds (hemoglobin, chlorophyll, etc) that get rather unique\n\ndo a little research, if some one cannot explain how they got the answer to a T/F question, you can't be sure they are just guessing

Most Common Element\nHydrogen is the most common element in both the Universe and the Solar System. Over 90% of the Universe is comprised of hydrogen. -----Iron is the most common element on Earth,----- accounting for 36% of its mass.

The most abundant element in the universe is hydrogen.  Nebulae are made up most of that and "dust".

oxygen, nitrogen, every fuckin mineral and more on the periodic table...take chemistry

Carbon, Hydrogen, and oxygen are what they are essentially made of but there are many different elements in the human body, that come through consumption.

A chemical element, often called simply an element, is a substance that cannot be decomposed or transformed into other chemical substances by ordinary chemical processes. All matter consists of these elements and as of 2006, 117 unique elements have been discovered or artificially created. The smallest particle of such an element is an atom, which consists of electrons centered about a nucleus of protons and neutrons.

Carbon, Iron and Nickle. In that order I believe. \n\nThat is of the earth itself... If you mean of the planet including the atmosphere, then its Hydrogen and Helium.

Protons, neutrons and electrons.  Of course the first two are composed of something else, but that probably isn't what they are going for here.
