Atlantic Posted February 21, 2004 Share Posted February 21, 2004 What would you say would be most metallic and non-metallic? Link to comment Share on other sites More sharing options...
Quantum Defect Posted February 22, 2004 Share Posted February 22, 2004 It depends how you see it. I suppose the most metallic (non-radioactive) element is Cesium, but Francium would be the most metallic element if you consider the radioactive ones, while the most non-metallic element is Fluorine...if we exclude the noble gases since they are not so reactive.

Atlantic Posted February 22, 2004 Author Share Posted February 22, 2004 cesium has low melting point and Not very ductile and malleable if you ask me Would aluminum be up there? btw for those who don't know or don't remember: properties of metals: dense, solids, grey, shiny, malleable and ductile, conduct electricity and heat, and have a high melting point.

wolfson Posted February 22, 2004 Share Posted February 22, 2004 I think as long as the element is in 1 molar quantity then they are "most" metalic, even if they do not pass electricity as good as another they still remain metallic. Link to comment Share on other sites More sharing options...
YT2095 Posted February 22, 2004 Share Posted February 22, 2004 then going on pure physicalities and NOT chemicaly then I`de hazard to say off the top of my head (and I may probably change my mind on deeper thinking!). metalic: a cross between Tungsten and copper Non metalic: as a solid at RTP then: Phosphorous, as a non solid then: Helium all based entirely on personal opinion and not scientific fact!

Atlantic Posted February 22, 2004 Author Share Posted February 22, 2004 tungsten is my choice too, I am not sure for non-metallic, either helium or Flourine Link to comment Share on other sites More sharing options...

Metals are generally classified by their free electron sea. Saying that metals must be solid is wrong (Mercury, melted metals). Similarly 'grey' (gold), dense and high melting point. You can express things in terms of their ionic character, but that's not exactly saying 'how metallic' a thing is. Anyway, metallic isn't an analogue state; it either is a metal or it isn't.

Crash Posted February 23, 2004 Share Posted February 23, 2004 I thought that the delocalized electrons only counted for a small bit, as allotropes of carbon, ceramics and other not 100% metals can also have this property Link to comment Share on other sites More sharing options...

Benzene rings, for instance, can display some properties linked with a metallic bonding method, but it's a different structure entirely. Link to comment Share on other sites More sharing options...

Atlantic Posted February 24, 2004 Author Share Posted February 24, 2004 what does electronegativity has to do with being metalic? Its not a property is it? Link to comment Share on other sites More sharing options...
Crash Posted February 24, 2004 Share Posted February 24, 2004 ? all atoms have electronegativity but it deals with bonding, although the electronegativity has a patern on teh periodic table this dosent have any special means of of determining metals from non metals........although caseium and francium have the lowest electronegativity values while flurione has the highest(pauling scale) Link to comment Share on other sites More sharing options...
Guest lorie nelsen Posted May 4, 2005 Share Posted May 4, 2005 help! I'm new! Anyone know how to collect platinum shavings out of iron and gold dust? Need imedeatly!! Link to comment Share on other sites More sharing options...
xa Posted May 5, 2005 Share Posted May 5, 2005 Well I suppose you could get rid of the iron with a magnet, dunno about the gold. Also if it's pure iron and gold I doubt you'd get platinum out of it. Link to comment Share on other sites More sharing options...
H2SO4 Posted May 5, 2005 Share Posted May 5, 2005 help! I'm new! Anyone know how to collect platinum shavings out of iron and gold dust? Need imedeatly!! DId you know you can start a new thread? this just totaly interupted this one. As for the metal thing, i think if its metal it metal, if its non-mrtallic its non-metalic. To me Cesium is just as mettalic as iron, copper, silver, platinum and tungsten. My favorite metal is probaly copper. I love the color and its properties. My favorite non-metal is probaly oxygen. As for you question lorie nelson, now that youve removed the iron, you could proably use density to seperate Pt and Au. There both very dense but Pt is more dense. If that doesnt work your last resort would probaly be aqua regia, but that would suck because you dont want to waste gold. Although, platinum is of higher value than gold (i think).

mmalluck Posted May 5, 2005 Share Posted May 5, 2005 I'd have to say Silver is my favorite metal. It's nice, soft, shiny, and the king of conductivity. I just wish it didn't tarnish so quickly. I'd say helium is about as non-metal as you can get. Link to comment Share on other sites More sharing options...
H2SO4 Posted May 5, 2005 Share Posted May 5, 2005 silver doesnt tarnish terribly quickly, but it is a pain. It forms (i believe) sulfur compounds from the sulfur dioxide in the air and other sulfur compounds in eggs. Silver is pretty interesting. I touched a piece of silver to an ice cube and it cut through it like butter because its thermal conductivity. Not terribly expensive either. Diamonds, however, are even better for cutting through ice. Link to comment Share on other sites More sharing options...
Mendelejev Posted May 5, 2005 Share Posted May 5, 2005 Here are my favourites : Metal : I think Mercury : dense, liquid, shining. Or maybe cesium with his color of gold and also liquid but so extremely dangerous. Non-Metal : mmmm, difficult. Maybe hydrogen, so simple but so usefull. Or bromine, dark-red liquid with a lovely odor Link to comment Share on other sites More sharing options...
AzurePhoenix Posted May 5, 2005 Share Posted May 5, 2005 I believe hydrogen sometimes exists in a nearly or even fully metallic form. Link to comment Share on other sites More sharing options...
budullewraagh Posted May 5, 2005 Share Posted May 5, 2005 favourite metals: gallium, bismuth, osmium/indium, neodymium, cesium, strontium, indium favourite nonmetals: phosphorus, fluorine, bromine, iodine Link to comment Share on other sites More sharing options...
H2SO4 Posted May 6, 2005 Share Posted May 6, 2005 Favorite metal: copper, silver, magnesium, aluminum, and bismuth. I like alll metals, but these are my top favorites, especialy Cu and Mg. Link to comment Share on other sites More sharing options...
