Which, non alloyed, metals are magnetic; and which metals are non-magnetic?

I will get you started on the exact answers to this, my friend.  But I am not going to do all your work for you.\n\nGo to http://myweb2.search.yahoo.com/search?fr=ks&p=paramagnetic+elements \n\nOnce you pull that up and start reading, it will lead to all the rest fairly directly.\n\nBe sure to groove on each definition to get the exactitude of it -- magnetic, paramagnetic, diamagnetic, etc.\n\nTry to learn something about the electron configurations involved.\n\nAll good things take some work, you will learn better if you do it yourself while taking notes.

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 generally form positive ions. Nonmetals generally form negative ions. The major exception is Hydrogen, a nonmetal that predominantly forms positive ions.

ferrous is magnetic and non-ferrous is not magnetic.

All materials that contain iron will rust, unless it contains very high amounts of carbon such as stainless steel that is. the simple answer to this question is all ferrous metals "rust" almost all others oxidise. oxidisation is caused when Oxygen and Water vapour attack the surface. the only natural metals that do not rust or oxidise are Gold and Silver. there are other exceptions too such as stainless steel but this is a man made alloy. A simple rule of thumb. if a magnet will stick to it. it will rust. another observation is when blood dries it goes a rust colour, this is because it contains high amounts of IRON

I'm not sure anyone really "know" but there are many teltail clues.  Not all materials are magnetic except perhaps under very powerful magnetic fluxes (MRI's?) but all atoms of materials do have one or more electrons orbiting their nuclii.  We know that electrons can be directed by magnetic flux, perhaps in a TV picture tube, etc.  Therefore, the number and arrangements of electrons of the atoms differ and some create magnetic properties (dipoles or two different poles).  If an iron bar is heated to a high temperature all the iron atoms in the bar are permitted to spin around willy-nilly.  If the bar is then cooled while exposed to a strong magnetic flux (electromagnet?) all its dipoles will align uniformly with the external flux like the needles of compasses aligned with the earth's flux.  When cool, the magnet exhibits the combined strength of all the dipoles that were previously working against each other.  We know that atoms repel each other because of their electrons (and even their nuclii must be forced together to fuse because of protons) like basketballs with ballbearings at their centers, where the skins are made of rapidly orbitting electrons.  Whereas the basketballs would repel each other in any given positions, actual atoms in iron crystals repel directionally and they which can attract or repel a free electron.  The magnet has collectively directed their combined force.  If each dipole has a North and South pole, we would expect the entire magnet to also have a North and South pole, and for like poles to repel, just as in the individual dipoles.  Hope that helps a little.

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.

Not Steel, but steel alloys.  In particular, stainless steel alloy.

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

Possibly. The only metals that are ferromagnetic are iron, nickel, and cobalt. Selenium is a completely different element, so if it's pure selenium, it won't show up. \n\nHowever, the aztecs probably didn't have pure selenium - it likely contained some iron. So it would show up.

For common metals, iron is pretty much all you have.  Magnetite is an oxide of iron that is the about the most magnetic metal on earth.\n If you are looking for low weight, rare earth magnets are the way to go, but will cost you accordingly.  Neodymium or Samarium-Cobalt are your best bets there.

The three types of ferrous metals are cast irons, steels, and iron.\n\nThe link will give applications of each.

An alloy is a metal with more than one element. Hydrogen is the lightest element, a gas, colorless and flavorless. And explosive.

Yes, Titanium is a non-ferris (not magnetic) metal and will not harm you when/ if you have an MRI, though the screws look cool on the film

Metal having iron in small amounts is known as a ferrous metal. It can be an imourity as well. And those which dont are non ferrous metals
