A polar molecule usually contains polar bonds - bonds which have unequal sharing of electrons between the two atoms involved in bonding. Examples are salts, acids and bases. A non-polar compound usually contains non-polar bonds - bonds which have identical or similar sharing of electrons. Examples are oils and hydrocarbons.\n\nCitric acid is polar.

Non-ferrous metals are metals that do not contain iron. There are two groups of metals; ferrous and non-ferrous. Ferrous metals contain iron, for example carbon steel, stainless steel (both alloys; mixtures of metals) and wrought iron. Non-ferrous metals don't contain iron, for example aluminium, brass, copper (which can be remembered as ABC) and titanium. You can also get non-ferrous metals as alloys eg, brass is an alloy of copper and zinc.

IT could be diamagnetic according to electron configuration from Chemistry. But without specific formula I would say your best bet is e nomagnetic.

it is a noble gas, but just because something isnt solid doesnt meanits a nonmetal. metals all become gasses at high temperature. the metals are on the left side of the periodic tabl and the non metals arre on the right. xenon is all the way on the right so its a non metal.\n\nhttp://en.wikipedia.org/wiki/Periodic_table#Standard_periodic_table

Carbon Tetrachloride is a non-polar molecule, thus it is capable of dissolving similar non-polar molecules.

metals: give up electrons in ionic bonds. They also form metallic bonding.  sodium, potassium, lithium, to name just a few. There are a lot of metals\n\nnonmetals: this is more more difficult group to describe. They materials like to form covalent bonds--a joint sharing of two electrons. Both hydrogen and oxygen are nonmetals. But hydrogen gives up its electon in an ionic bond. For example HCl. It that repect it acts similar to a metal. Carbon is also a nonmetal\n\nMetaloid: silicon, germanium, boron, arsenic, antamony. These elements are right on the line between metals and nonmetals. As a result they make good semi conductors.

Yes, these are called endohedral fullerines.  Some molecules of C60 were found with forms of helium trapped inside in the Sudbury crater in Ontario (endohedral heliofullerines).  \n\nSome paleobiologists hypothesize that the pre-biotic chemicals that led to the development of life on earth were transported inside of C60 polyhedrons on the surface of meteorites.  There is also a significant amount of medical research around potential uses of "Buckeyballs" to safely deliver toxic medicines to specific cells or to bacteria, or to encase radioactive metals in resonance imaging, which would shield the patient from the radiation.  \n\nAs a side note, when "Buckeyballs" (short for Buckminsterfullerine) are doped with metallic atoms, they are called "Dopeyballs."  If the opportunity ever arises to use the word Dopeyballs in a sentence, I would highly recommend it.  :)\n\nAnd as for the strength of the molecule, endohedralism has no effect on the bond strengths within the C60 molecule itself, because the encased molecule and the C60 are both electrochemically inert; if anything, I would imagine that if an encased chemical exerted some attractive or repulsive force on the C60 cage, it may weaken its structural integrity.  Dopeyballs (yay!), on the other hand, are significantly stronger and more resilient due to the strong bonding and electron pull of the incorporated metal atoms.
