What does a particle model of rust (iron) look like?
476743
Rust is made of Iron (III) Oxide, not pure iron.  As for its crystal structure, I'm not completely sure.

The simplest reasonable model of the atom is the Bohr model, which does tend to look like a mini solar system. In actuality, atomic structure is not so easy to define. The further you advance in chemistry, the more complex the models become, and the less they look like "mini solar systems". But they are still only reasonable attempts to visualize a very complex system, and cannot physically confine all the expected paths of the electrons' orbits.

Almost all of them actually. The rusting of iron forms a red colour,  the burning of a match forms a black color and so forth. Think of any chemical reaction and it will most likely include a colour change.

Rusting is a type of oxidation.  Iron forms a compound with oxygen, iron(III) oxide or ferric oxide, which we call rust.\n\nA screw can be made from steel, aluminum, titanium, bronze, or even plastics like Teflon or nylon.  A screw can be made from pretty much any structural material.

ya, rusting is called "oxidation" because the iron reacts with the oxygen in the air to produce iron oxide:  Fe + O2 -> Fe2O3  iron oxide = rust.\n\nanyway, if you coat the iron with a film of something, the air can't get to the iron and voila, no rust!  this is also why things that rust are painted - paint does the same thing.\n\ni'm not sure how to answer the 2nd part of your question - doesn' make sense and to be honest, just doesn't jive with my experiences.  sorry!

three legged matel object mostly of iron...used as a stand to place beakers, funnels etc when heating them.

Aluminum will oxidize, but the aluminum oxide forms a coating over the remaining aluminum that prevents further corrosion.\n\nBy contrast, iron oxide (better known as rust) will not form such a coating, it will warp and crumble and expose more iron to rust.

Real rust is oxidized iron and so it can only be one color.

Haemoglobin, which is made red by the presence of iron. Just think of your blood as rusty.

If you crush your chips up, then weigh out an equal amount of each (say 10 grams), put the crushed chips in some acid solution (say 100mls of 10% hydrochloric acid) and shake them up good, the iron should come out into solution.\n\nThen you could measure it using whatever you have access to.\nAA, some kind of colorimeter...

I am not sure about rust, but I know that each 12 ounce can of Coke contains 10 teaspoons of sugar.  (That is what my chemistry college professor told me).

more likely iron then steel

The more surface area is open to the air, or oxygen, the faster it rusts.  That's why a sheet, which is pretty much totally exposed, will rust fast, but not thick parts like the engine, etc.  Rust, after all, is the product of Iron mixing with Oxygen.  Also, steel is a mixture, more specifically a metal alloy, of iron with carbon.  Alloys with higher carbon content than this are known as cast iron.  Therefore, cast iron rusts slower than sheet metal also because it contains a lot of carbon, rather than being all iron.  I don't know what is better for the garden, but "cast iron" is actually steel, with high amounts of carbon in it.

Rusting or corroding is the wearing away of a metal layer that leads to formation of metal compounds on the surface. Rust is a compound that forms on top of iron. Blackening of silver is another example

Many thin rods totaling the same volume as one pile will have far more surface area.  Rust only occurs on exposed surfaces.  Therefore, there will be far more rust on a structure made of many small rods as opposed to one made with thick piles.

if metal rusts, the iron is being oxidized so it is a chemical change.

well u might hav seen enough picts/diagrams showing such field lines.\n\ntry this experiment.\nplace a barmagnet under a cardboard/examboard etc. then throw some iron fillings on the board. U will c that a pattern exactly like the one shown in diagrams is obtained.\n\ni guess this little 'experimental' proof satisfies u.
