Titanium is amongst them. Tungsten and wolfram too. That's all i can think off right now.

4Cr + 3O2 --> 2Cr2O3\nChromium(III) oxide or Chromium oxide.

Yes, they do. The simplest example I can do is Fe (iron): it's a transition metal and has 3 oxidation states: 0 (Fe as a metal), +2 (FeO), and +\n3 (Fe2O3).

what you need to do, get a SI data book, and look up their natural state. not bonded with anything else, and possibly itself.\n\nPhophorus - white: molecular (P4). red: Chain. Black: Layer\nIodine - molecular (I2)\nMagnesium - hexagonal closest-packing\nNeon - cubic closest-packing\nArsenic -grey: 3d structure - Layer formation. yellow: molecular As4\nSulfur- molecular S8\nBoron - complicated structure.\nSelenium - grey: chain, Red: molecular: Se8\nGallium - Complicated\nCesium - body-centred cubic\nOxxygen - O2, O3 molecular

You could use hot KMn04, but what about using a chromium oxidizing agent, such as Cr03 or NaCr04 ... you might get a cleaner oxidation.

Tungsten, or in German, Wolfram. This is why the symbol is W.

A hard brittle blue-gray or blue-black transition metal in the platinum family, osmium is the densest natural element and is used in some alloys with platinum and iridium. The extraordinary density of osmium is a consequence of the lanthanide contraction. Osmium is found native as an alloy in platinum ore and its tetroxide has been used to stain tissues and in fingerprinting. Alloys of osmium are employed in fountain pen tips, electrical contacts and in other applications where extreme durability and hardness are needed.\n\nand real close to it is Iridium

Actually the answer is Tungsten.  Rhenium is close, boiling at 5627c (9,668.93 degrees Fahrenheit), but the king of boiling points is still Tungsten at 5660c (10,220 degrees Fahrenheit)\n\nThere could be others, but many elements don't really stick around long enough for us to test their boiling point.

They are all row three transitions metals.  So the point about 5 valence electrons is correct depending on the oxidation state of the atom.

Tungsten (formerly wolfram) is a chemical element that has the symbol W (L. wolframium) and atomic number 74. A very hard, heavy, steel-gray to white transition metal, tungsten is found in several ores including wolframite and scheelite and is remarkable for its robust physical properties, especially the fact that it has a higher melting point than any other non-alloy in existence\n\nPhysical properties \nPhase solid \nDensity (near r.t.) 19.25 g/cm³ \nLiquid density at m.p. 17.6 g/cm³ \nMelting point 3683 K\n(3410 °C, 6192 °F) \nBoiling point 5828 K\n(5555 °C, 10031 °F) \nHeat of fusion 52.31 kJ/mol \nHeat of vaporization 806.7 kJ/mol \nHeat capacity (25 °C) 24.27 J/(mol·K) \n\n\nList Of elements by melting point:\n\n\nName Symbol Melting Point (°C) \nHelium He (Does not solidify\nat normal pressure\neven at absolute zero) \nHydrogen H -258.975 \nNeon Ne -248.447 \nOxygen O -222.65 \nFluorine F -219.52 \nNitrogen N -209.86 \nArgon Ar -189.19 \nKrypton Kr -157.22 \nXenon Xe -111.7 \nChlorine Cl -100.84 \nRadon Rn -71 \nMercury Hg -38.72 \nBromine Br -7.1 \nFrancium Fr 27 \nCaesium Cs 28.55 \nGallium Ga 29.76 \nRubidium Rb 39.64 \nPhosphorus (white) P 44.1 \nPotassium K 63.35 \nSodium Na 98 \nIodine I 113.5 \nSulfur S 115.36 \nIndium In 156.76 \nLithium Li 180.7 \nSelenium Se 221 \nTin Sn 232.06 \nPolonium Po 254 \nBismuth Bi 271.52 \nAstatine At 302 \nThallium Tl 304 \nCadmium Cd 321.18 \nLead Pb 327.6 \nZinc Zn 419.73 \nTellurium Te 449.65 \nAntimony Sb 630.9 \nNeptunium Np 640 \nPlutonium Pu 640 \nManganese Mn 649 \nAluminium Al 660.25 \nRadium Ra 700 \nBarium Ba 729 \nStrontium Sr 769 \nCerium Ce 798 \nArsenic As 817 \nEuropium Eu 822 \nYtterbium Yb 824 \nCalcium Ca 839 \nEinsteinium Es 860 \nLanthanum La 920 \nPraseodymium Pr 931 \nPromethium Pm 931 \nGermanium Ge 938.3 \nSilver Ag 961 \nBerkelium Bk 986 \nAmericium Am 994 \nNeodymium Nd 1016 \nActinium Ac 1050 \nGold Au 1064.58 \nCurium Cm 1067 \nSamarium Sm 1072 \nCopper Cu 1084.6 \nUranium U 1132 \nMagnesium Mg 1244 \nBeryllium Be 1278 \nGadolinium Gd 1312 \nTerbium Tb 1357 \nDysprosium Dy 1407 \nSilicon Si 1410 \nNickel Ni 1453 \nHolmium Ho 1470 \nCobalt Co 1495 \nErbium Er 1522 \nYttrium Y 1526 \nIron Fe 1535 \nScandium Sc 1539 \nThulium Tm 1545 \nPalladium Pd 1552 \nProtactinium Pa 1600 \nTitanium Ti 1660 \nLutetium Lu 1663 \nThorium Th 1755 \nPlatinum Pt 1772 \nZirconium Zr 1852 \nChromium Cr 1857 \nVanadium V 1902 \nRhodium Rh 1966 \nTechnetium Tc 2200 \nHafnium Hf 2227 \nRuthenium Ru 2250 \nBoron B 2300 \nIridium Ir 2443 \nNiobium Nb 2468 \nMolybdenum Mo 2617 \nTantalum Ta 2996 \nOsmium Os 3027 \nRhenium Re 3180 \nTungsten W 3407 \nCarbon (diamond) C 3550 \nCarbon (graphite) C 3675 \nCarbon (amorphous) C 3675

Sb shows -3 +3 and +5 oxidation states, it belongs to N family. Having more metallic character, it exhibits cations as in Sb2O3
