which of these elements is not naturally in it's elemental state?

sulfur forms S8...Cl forms Cl2...O is found as O2...N as N2\n\nps im a chem prof so i know;)

Some atoms do not loose their electrons easily.  These can either share electrons (like carbon usually does) or snatch electrons from other atoms to become negative ions (like Fluorine does).  Most metallic elements easily loose electrons to become positive ions (like sodium Na - e- = Na+).

Cause they are not metals...?\nI don't really understand what you're asking, but what I can tell you is that S and I are both on the right side of the periodical table and therefore both are non-metals.

Not clear what you are asking.\n\nIf you are asking if any elements exist as pure elements, not in any compounds, the answer is "no".\n\nBut there are quite a few elements that make up the human body in various proportions.  Carbon, Hydrogen, Oxygen, Sodium, Potassium, Chlorine, Nitrogen, Sulfur, Phosphorus, Iron, Magnesium, Calcium make up a good bit of your body.  But it is how they are combined that is important.

Mercury\n\nA heavy, silvery, transition metal, mercury is one of five elements that are liquid at or near standard room temperature (the others are the metals caesium, francium, and gallium, and the nonmetal bromine)

Lithium is very reactive, especially as a metal interacting with water. I would classify boron as reactive.

Zirconium is a metal (transitional metal, to be precise).\nChlorine is a non-metal (halogen).\nGold is a metal (also a transitional metal).\nUnunnilium (now called darmstadtium) is a metal (transitional metal, too.).

They can be called main group elements which doesn't include the transition metals or the lanthanides.

If by "naturally occuring" you mean present in nature in its elemental form, then the answer includes noble gases (Helium and Argon), noble metals (Gold and Platinum and maybe Copper), and some diatomic molecules (Oxygen, Nitrogen) as well as Sulfur (S_8) and Carbon (graphite and diamond).  Most of the metals are found as some kind of oxide (in ores) or in salts (sodium chloride).  The halogens are found in salts (sodium chloride). \n\nA lot of today's useful materials were never present in significant amounts in elemental form, for example: iron, aluminum, zinc.

http://www.chemicool.com/definition/element.html\nis this what you mean? \n\nI don't think that this is a physical property although for the life of me I can't see why it couldn't be.

There would be no liquid nonmetallic element!!

Do your own homework girl!\n\nNon-metals are the elements in groups 14-16 of the periodic table. Non-metals are not able to conduct electricity or heat very well. As opposed to metals, non-metallic elements are very brittle, and cannot be rolled into wires or pounded into sheets. The non-metals exist in two of the three states of matter at room temperature: gases (such as oxygen) and solids (such as carbon). The non-metals have no metallic luster, and do not reflect light. They have oxidation numbers of ±4, -3, and -2. \n\nThe Non-Metal elements are: \nHydrogen \nCarbon \nNitrogen \nOxygen \nPhosphorus \nSulfur \nSelenium

Halogens, in their elemental state, are covalent. In their elemental state, they are not compounds, because they are not combined with other elements. But F2, Cl2, Br2, I2, and At2 are covalently bonded.

Magnesium is an element it does not "break down".

Some metallic and some non-metallic.\nLike Silicium... it it shiny, just like metals, but doesn't conduct electricity, just like non-metals.\nOr Carbon... it is not shiny and doesn't react with acids, like non-metals, but conduct electricity, like metals.
