Does a element have only one atom?

guys answered question before me got bit wrong.
element basic name kind of atom exact number of protons in nucleus. therefore dont element has 1 atom. say: oxygen element.
o - yes, says single oxygen atom, wont find in nature, sign of element oxygen
o2 - molecule of oxygen, has 2 atoms in it, how found normally.
so, principal is, wont in chemistry, element has 1 atom, element doesnt how many, kind.
sum up:
element - "kind of atom" number of protons in nucleus.
atom - http://ut-images.s3.amazonaws.com/wp-con... thats atom, electrons, protons, neutrons. definition of atom: smallest particle, indivisible. (in chemical ways, divisible in physics - radiation)
molecule - more atoms (they stick chemical bond), can same kind (o2, h2, n2, s8) or different kind (h2o, h2so4, co2)
hope clearer now, if unclear, write in addition questin , edit answer. ;)

like o (oxygen) 1 atom 2 oxygen atoms (o2) still count element or molecule. confused on atoms, molecules , elements. please explain , use examples pick best answer :)

thanks!
