Nonmetal, or metal compound?

metal: simple element at room temp. except galium, mercury and cesium\n\nnonmetal: simple elemnent at the three states of matter

Tungsten mostly, but there are other metals used. There are also gasses that glow too in bulbs that have no filiment wire.

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.

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.

I think it's these metals chrome, cobalt, titanium, or ceramic materials can be used.  I think they have recalled ceramic because they were cracking though.

francium. mercury is technicaly not a metal, it just has a low melting point, low metling points do not make it unstable. if that were the case, then oxygen would be VERY unstable ITS ALREADY TURNED INTO VAPOR!!!

Because it's a reactive form of metal and can easily form compounds. You wouldn't want a material in your body that's reactive otherwise you will be looking for more trouble.

I'm sorry...my answer to this question, will either sound really smart or really stupid. \n\nMy AP Chemistry class just finished the chapter on bonding. We learned of Ionic bonds, Covalent Bonds, and Hydrogen bonds. \n\nAn ionic bond is a bond between a metal and non-metal and involves the transferring of electrons so that both atoms will become stable but with opposite charges, become attracted to each other, and form a molecule. An example is NaCl or table salt. Na is a metal, Cl is a non-metal.\n\nThe next is covalent bonding between two non-metals or non-metal and metal and involves sharing electrons. An example is O2 - oxygen.\n\nFinally hydrogen bonding is self-explanatory consisting of hydrogen and another element.\n\nBecause of the above, it is chemically impossible for two metals to bond as they will not have enough electrons to stabilize each other in the first place. \n\nI even performed this experiment in class. When a metal is heated it "oxidizes". Its atoms fuse with the oxygen atoms in the air and form the gas. For this reason a metal starts turning brown, as you are simply speeding up the process of rusting.\n\nSo your question is kind of impossible from what I have learned in class. \n\nI'm sorry if I am completely of the point in this answer (if there is something I am not getting and that two metals can actually bond) and I apologize for my ignorance and stupidity in advance. haha

aluminium because its an alkali earh metal and\nfluorine is a halogen

If it's metallic, it could be sodium or potassium.

Connection? or disconnection...\n\nSemiconductors are not metals - nor do they intend to be.

Sodium, Potassium, Barium\n\n As long as the metal is more reactive than magnesium, it will be able to displace magnesium ion.

Indeed, it is the metal. \n\nThe accompanying in is usually NO3 or SO4--Colorless!!\n\n\nGet an "A".

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.

HgO ------> Hg + O2 at about 400 C\n\nMg + CuCl2 ---------->  MgCl2 + Cu(solid)\n\nMg, being higly electropositive than Cu, replaces Cu.
