Which metal has the highest boiling point ?and how much is it?
363084
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.

Iridium, a metal of the platinum family, is white, similar to platinum, The specific gravity of iridium is only very slightly lower than osmium, which is generally credited as the heaviest known element. Calculations of the densities of iridium and osmium from the space lattices give values of 22.65 and 22.61 g/cm^3, respectively. These values may be more reliable than actual physical measurements. At present, therefore, we know that either iridium or osmium is the densest known element, but the data do not yet allow selection between the two. Although its principal use is as a hardening agent for platinum, iridium is also used to make crucibles and devices requiring high temperatures. It is also used for electrical contacts. \nThe element forms an alloy with osmium which is used for tipping pens and compass bearings.

While Glass is technically not a metal being composed of silica compounds of various types, the quickest cooling true metal is mercury...yes mercury is a metal...titanium is next followed by bauxite the main ingredient in aluminum.

Na+ and K+ (both group 1)\nCa2+ and Mg2+ (both group 2).\nNa+ and Mg2+ have the electron arrangement of neon, and the other two that of argon.\nIonic radius decreases from left to right, and increases top to bottom, so K+ is the largest of all these.\nElectronegativity increases upwards and to the right of the Periodic Table, so Mg has the highest value of these four.

Traditionally, metals have certain characteristic physical properties: they are usually shiny (they have "lustre"), have a high density, are ductile and malleable, usually have a high melting point, are usually hard, and conduct electricity and heat well. However this is mainly because the low density, soft, low melting point metals happen to be reactive, and we rarely encounter them in their elemental, metallic form. Metals are also sonorous, which means that they conduct sound well.\n\nAnd not all metals are magnetic!\n\nPalladium is a soft silver-white metal that resembles platinum. It doesn't tarnish in air. Palladium is the least dense and has the lowest melting point of the platinum group metals. It is soft and ductile when annealed and greatly increases its strength and hardness when it is cold-worked. Palladium is chemically attacked by sulfuric and nitric acid but dissolves slowly in hydrochloric acid. This metal also does not react with oxygen at normal temperatures.

The previous poster is right:  Gold is the most ductile metal.  "Since the cohesive forces are strong and the atoms do not become widely separated from each other during their rearrangement, the metal holds together while its shape is being changed."

Solid. Most elements at standard atmospheric temperature and pressure are solids. Some of the non-metals are gases, but only Mercury and Bromine are liquids at STP.\n\nEDIT: Gloo-gal, why answer if you don't know or don't care?

One of the things which effects the boiling points of substances is the intermolecular forces of attraction between the particles....the higher thr attractive forces, the higher the boiling point.\n\nWhich molecule has the higher attractive forces, Methane (Ch4) or Ammonia (NH3)?\n\nSince Methane is a small, nonpolar, hydrocarbon, the only attractive force its molecules experience is london forces (AKA induced dipoles).\nAmmonia on the other hand not only experiences london forces, but also experiences one of the most attractive forces...Hydrogen bonding.  The Hydrogens on the ammonia molecule are held in a polar bond with the Nitrogen making them form a partial positive charge and the Nitrogen forms a partial negative charge.  When the partial + Hydrogens from other NH3 molecules get near the parial - Nitrogens, they are attrcted to eachother which raises the boiling point of the substance.\nFor this reason, Ammonia gas will have a higher boiling point than methane.  This is confirmed by looking at the actual boiling points for each gas.\n\nBOILING POINTS:\nAmmonia: -33.5 degrees C\nMethane: -161.6 degrees C

Water's boiling point is 100 degrees Celcious (212 Fahrenheit), at zero altitude. Altitude can change the boiling point for water.\n\nYou can calculate that if you know your altitude, by following the link provided below.

Are you referring to radioactive decay rates of isotopes of the three elements (copper, aluminum and iron) that you listed? If so, the first answer gave you some info, but you should check it (e.g., because copper has more than one isotope and they all have different half-lives). One can't specify a half-life for stainless steel because it's a mixture of metal elements whose ratio isn't specified by the generic name.\nIf instead you're referring to some measure of chemical activity, such as corrosion life, you haven't given enough details. (Well actually you haven't given enough details either way.) You could google corrosion rate, reaction rate and similar terms if you want to go further with that.

Al has a higher boiling point because the molecules are bonded in a giant covalent structure, similar to silicon. Na, although a metal, only has metallic bonding between the molecules which tends to be weaker than giant covalent bonding.

Boiling point depends on the strength of the intermolecular forces. Following is the list of them all with their strength and when they occur. \nnetwork covalent (strongest) with only diamond or SiO2\nIonic (ionic compound, 2nd strongest) like Na-Cl etc. Gets stronger with smaller sizes. \nHydrogen bonding (N, O, F with H) 3 rd strongest. \nDipole dipole (when there is a polar molecule) 4 th strongest, gets stronger with more polarity. \nLondon dispersion weakest. Stronger with more mass. \n\na NH3of the first two. Because NH3 has hydrogen bonding (only if you have N, O, or F with hydrogen) while PH3 has regular dipole dipole (based on polarity), which is weaker than NH3. \nNow in this one its c because if you draw their Lewis diagrams out c molecule has on O----H bond while d doesn't. That hydrogen bond is strong enough to make c stronger. As other than that they only have London dispersion force, (which are found in non polar molecules, and they get stronger as atomic mass gets higher). \ne and f both have the London dispersion force that I talked about earlier cause they both are non polar. So f has greater mass so f has higher boiling point. \ng because HCl has polarity (dipole dipole forces) which are stronger than F2 which is non polar and has London dispersion forces (they are the weakest).

Hmmm.. The one affecting the boiling point is the intermolecular force..\nAs you can see, most of the compound here is polar. \n\nTherefore all you have to do is if the compound is consisted only of 2 elements (Group 17), you'll have to calculate the electronegativity difference. The more difference between them, the boiling will increase as well.\n\nIf there is more than 2 atoms in a molecule, you'll have to see the dipole moment magnitude (a.k.a polarity). The higher the magnitude, the higher the boiling point will be.\n\n\npeace\nvixklen
