Question

Is the human body made out of the whole periodic table? If it's not, what is it made out of?

Answer 1

Or uranium or einsteintinium either!

Answer 2

Mostly C,H,O,N,S,P.  But many other elements.  We do not know all necessary trace elements.  I'm sure you've heard that most of the body is H2O.

Answer 3

I'm PRETTY sure we don't contain any plutonium.  Or neon.  Hmmm.

Answer 4

There are traces of all naturally occurring elements (including uranium) in humans.  Even for noble gases, there are a few atoms dissolved in blood, etc.  This does not mean that all are necessary or beneficial.  As another answerer mentioned, it is not known which of these are required for humans.

The main elements present in the body are (in decreasing order) O, C, H, N, Ca, P, K, S, Na, and Cl.  Trace elements include Mg, Fe, Zn, Cu, I, Se, Co, Mn, Ni, and Mo.  Other elements thought to possibly be essential, but not proven, include Cr, V, Sn, and even As!

We also take in a lot of Sr, Br, and Rb, due to their chemical similarity with Ca, Cl, and K, respectively.
