Tel such a metal's name that cannot be break by another metal & which can be melt by any acid?

Such a metal does not exists

Tungsten is a fairly cheap metal (compared to the precious metals) which is very dense, has one of the highest melting points of all metals, and is resistant to acids (though not as resistant as gold or platinum)

metallic if it is bonded to another metal or ionic if it is bonded to a non-metal.

yes, with an alloy or equal or lower melting point

METALS ARE MALLEABLE AND DUCTILE INDEED THEY ARE VERY STRONG SOME METALS LIKE ALUMINIUM HAS A LOW DENSITY SO IT'S USED IN BUILDING AIRCRAFTS,IOW DENSITY COOKING UTENSILS ETC.. ALLOYS EG:STEEL IS ALSO USED IN UTENSILS ....COINS ARE ALLOYS OF NICKEL AND COPPER.....METALS USUALLY HAVE A HIGH MELTING POINT.......

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

Guess a group 3 metal such as boron or Aluminium

High tensile strength steel...however there are other non-metals that are actually stronger...carbon fiber materials being one possibility.

since a "certain" soft metal on burning produces lime  lime cannot be an element . hence the answer is 'c'\nanswer : 'c'\n  note: the soft metal is calcium

copper, silver, aluminum, lead, magnesium, platinum and tungsten

Any metal will melt on heating (unless burning up before), but for pure lead the melting point is fairly low with 600K (327°C, or 621°F). The melting point for lead alloys (with tin and/or antimon) is even lower.\n\nEven candle flames emit sufficient heat to melt down lead placed on a spoon in reasonable time.

haven't you seen magnesium burning. sodium burns, potassium burns.\n\nthese metals are very reactive metals owing to the valence electrons in their atoms. they are one electron short of stable octet structure (mg- 2 elec), and so they easily burn\n\nbut other metals are much stable and the oxides of those metals are formed at very high temp and long exposure time but not accompanied by emission of flames.\n\nwood is made of cellulose, which is organic in nature i.e carbon and hence burns to form carbon di oxide (chiefly present in smoke)

Heavy Metal! Just joking. http://www.scienceproject.com/projects/intro/elementary/EX057.asp Go here, they have a lot of information.\n\nhttp://www.science.ca/askascientist/viewquestion.php?qID=1216 And this one. It is clear that aluminum conducts the best heat.

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.

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

Iron = Transition Metal\nCobalt = Transition Metal\nSodium = Metal (oddly enough)\nOxygen = Nonmetal (gas)\nHelium = Nonmetal (noble gas)

Zinc is by far the best element. I also like plutonium.  It's just fun to say. "Plutonium."
