On ading a non metal impurity to a metal what happens?

Depends on the metal. Most metals generally become brittle. Iron on the addition of Carbon hardens. You may say option 2.

When you want to balance ANY chemical equation, always follow these steps:\n\n1. Balance metals\n2. Balance non-metals\n3. Balance hydrogen\n4. Balance oxygen\n\nLet's do it\n\nFirst let's balance K (metal):\n\n"2" KHCO3 + __H3PO4 yields __K2HPO4 + __H2O + __CO2\n\ndone. now let's balance P (non metal): if you check, it is balanced already.\n\nnow C (also non metal):\n\n2 KHCO3 + __H3PO4 yields __K2HPO4 + __H2O + "2" CO2\n\nnow hydrogen:\n\n2 KHCO3 + __H3PO4 yields __K2HPO4 + "2" H2O + 2 CO2\n\nfinally, oxygen (its already balanced!!)\n\nSo you end with\n\n2 KHCO3 + H3PO4 yields K2HPO4 + 2 H2O + 2 CO2

it would be Covalentic ofcourse...\n\nIonic is usually when  Metal is reacting with non metal...\n\nin this case , both are not metals so it would be covalentic

nonmetals have much higher ionization energies than metals do. this is because non-metals have more protons in their nucleuses to attract their electrons with. metals do not have as many, as compared to the rows they are in, so the electrons will move away from the nucleus of the metal if given a little push.

Metals, Nonmetals, & Metalloids\n\nMost periodic tables contain a stairstep line which allows you to identify which elements are metals, nonmetals, and metalloids. Following are descriptions of each of the three types of materials.\n\nMetals\n\nMost elements are metals. 88 elements to the left of the stairstep line are metals or metal like elements.\n\nPhysical Properties of Metals:\n\nLuster (shininess) \nGood conductors of heat and electricity \nHigh density (heavy for their size) \nHigh melting point \nDuctile (most metals can be drawn out into thin wires) \nMalleable (most metals can be hammered into thin sheets) \nChemical Properties of Metals:\n\nEasily lose electrons \nCorrode easily. Corrosion is a gradual wearing away. (Example: silver tarnishing and iron rusting) \nNonmetals\n\nNonmetals are found to the right of the stairstep line. Their characteristics are opposite those of metals.\n\nPhysical Properties of Nonmetals:\n\nNo luster (dull appearance) \nPoor conductor of heat and electricity \nBrittle (breaks easily) \nNot ductile \nNot malleable \nLow density \nLow melting point \nChemical Properties of Nonmetals:\n\nTend to gain electrons \nSince metals tend to lose electrons and nonmetals tend to gain electrons, metals and nonmetals like to form compounds with each other. These compounds are called ionic compounds. When two or more nonmetals bond with each other, they form a covalent compound.\n\nMetalloids\n\nElements on both sides of the zigzag line have properties of both metals and nonmetals. These elements are called metalloids.\n\nPhysical Properties of Metalloids:\n\nSolids \nCan be shiny or dull \nDuctile \nMalleable \nConduct heat and electricity better than nonmetals but not as well as metals

d) bond to carbon\n\nThis nonmetal has the interesting chemical property of being able to bond with itself and a wide variety of other elements, forming nearly ten million known compounds.

Copper is more reactive than silver, hence displacement of silver occurs.\nCu (s) + 2AgNO3 (aq) --> 2Ag (s) + Cu(NO3)2 (aq)\n\nSum of the coefficients? 6...\n\nHope this helps :)

In chemistry, a metal (Greek: Metallon) is an element that readily forms ions (cations) and has metallic bonds. Metals are sometimes described as a lattice of positive ions (cations) surrounded by a cloud of delocalized electrons. The metals are one of the three groups of elements as distinguished by their ionisation and bonding properties, along with the metalloids and nonmetals. On the periodic table, a diagonal line drawn from boron (B) to polonium (Po) separates the metals from the nonmetals. Elements on this line are metalloids, sometimes called semi-metals; elements to the lower left are metals; elements to the upper right are nonmetals.

Zn is more reactive than Ni  (this is bcoz Zn is placed higher than Ni in the periodic table), so it would displace Ni from the solution of Ni(NO3)2. The reaction is \nZn + Ni(NO3)2 ----> Zn(NO3)2 + Ni

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.

Try this. Iron when combined with other metal elements becomes non-magnetic, yet with varying of the same elements is quite attracted to the magnet.Name the divisions of the metals and explain why.

a alkali will form a salt\na acid will not react\na metal will form a metalic sulphate and liberate hydrogen\n1)NAOH +H2SO4=NA2SO4+H20\n2)HCL +H2SO4=NO REACTION\n3)Zn+H2SO4=ZnSO4+H2

They would lose electrons.  metals lose electrons to obtain there octet.  \n\nNa, K would lose 1 electron\n\nMg and Ca would lose 2.\n\n\nwhoever said Ca would gain an electron is an idiot

Depends on the temperature. At a guess at melting point not that different from solid aluminum.

If I've understood what you're asking then:\nA\nCd(s) + Ag2+ -> Cd2+ + Ag(s) \n\nCadmium occurs at Anode and the Silver would deposit on the Cathode\n\nB (I hate Manganese equations and the partial above is incorrect)\n\nMnO2 + 4H+ + 2AgBr -> Mn2+ 2Br- + 2Ag + 2H2O\n\nMnO2 @ Anode\nAgBr @ Cathode\n\nC\n\n(PtCl4)2- + 4Ag -> Pt + 4AgCl \nAg @ anode\n(PtCl4)2- @ Cathode

The radioactive material would have degenerated, eventually degrading to non-radioactive metals. The radioactive material would be unstable, containing extra neutrons and protons, which the atom naturally wants to loose, to become more stable. Look up isotopes to explain theory of radioactive atoms, and such.
