Thank you,I think I am starting to understand now! Sorry I am very bad at chemistry but it is part of the course, so something like polyethelene or silicon carbide cant be shown as one atom in a image for example cant be something like example silicon carbide - xxneutrons xx protons xx electrons, there are many different atoms so it is not possible to show it as one atom? The tugsten, is that only one atom? because that atomic structure is shown (http://www.chemicalelements.com/bohr/b0074.gif) meaning there is only one type of atom used in it? Also if all that is correct, how many atoms do you think there would be in the materials I liseted, like silicon carbide? Thank you and again, I am sorry I am so bad at chemistry.

Thanks for the hlpful information. What is confusing me is that in the past I was told that every material has atoms that consist of a newcleus(protons/neutrons) and electrons orbiting it like this example for the tugsten http://www.chemicale.../bohr/b0074.gif (sorry dont know how I changed the colour of the text, cant change back ) so if this is true there should be images of atoms for the other materials, are you saying there is no images of the atoms for the other materials or do you mean there are many different types of atoms for each material? All I need is the picture of the atoms, not the strctures yet, just to confirm, you are saying that each material consists of many atoms and just one image of the atom is not possible to obtain?

Thank you, I am talking about these atoms: Tugsten: http://www.chemicale.../bohr/b0074.gif Polyethelene: I cant find an atomic structure, the one I showed above was wrong and the structre you showed me was written, I am looking for a structure like the others which is a nucleus with proton/neutorns and electrons obrbiting it. Silicon Carbide: http://mrsljones.wik..._bohr_model.jpg I think you had mentioned this is just silicon, just asking again to confirm because I need silicon carbide. Also I was just searching and found this: http://www.gold-aqua...ilicaimage3.jpg is this a correct crystal structure for silicon carbide (the one on the top right corner) or like the others does it not have one. Quartz Crystal Cant find any atomic structure Glass Fibre Reinforced Plastic I think you are right about this being fibre glass Cant find any atomic structure Shape Memory Polymer Is there not one basic atomic structure for a shape memory polymer? Cant find any atomic structure If you know of any websites that I could use to find the missing images please could you give me a link. Thank you

Thank you, you have helped me allot with all the information you have given me, I did as you said and asked my teacher today....turns out that we still have another lesson before we start the assignment, last lesson he gave us it and told what he basicly wanted but next lesson he was going to explain how we do it, he has given me a handout from the other group he did the lesson with and I am going to read that now, allready had a quick scan over it but going to spend my time and read it now, he has even made a chart showing what crystal structure the material is under, tungsten is under bcc, now the question becomes, why is there only tungsten, I read that some materials change there crystal structure at different tempratures so it is not possible to get a crystal for such materials, is this the case with most the materials listed above? Also, are the atoms I shown above in the links also incorrect? Just want to say thank you for helping me so far, I am learning loads of new information.

Ok, I will ask him next time I see him, thank you for your help, learnt loads of things from you so far thank you when you say compound what does that mean, do you mean there are different combintaions of elements for tugsten so there are loads of different types of tugsten? I saw something called "W" when I was looking for tugsten is that not just a tugsten atom on its own? EDIT: did some more research about compinds, by compunds do you mean things like sc, bcc?

Its research for the assignment, I need to get the images and describe them, how the atoms are conected explain about the structure and the structure, I just need to know what it looks like so I can explain it, drawin the atom is for additional information in describing the structure but describing is the main point of the assignment and that I will do myself.

I am geting the same problem again, just cant find 1 image, allways 10 or more different ones on one page. Could somebody help me find some images please?

Thanks for the help The thing that is cnfusing me is when I try typing something like tugsten crystal structure on google images I get about 10 different types of structures on the page, I just dont know what one I am supposed to be doing. Do you have any good images for a tugsten crystal structure and atom please?

They showed the class and example of what we had to do and they showed an atom (drawn) and a 3D atomic structure, the one they showed was like a cube with some atoms inside and another one where there was atoms sitting ontop of eachother like a chain of atoms, they asked us to do it that way, will it be very hard?

Wow thank you, very descriptive, just what I needed great help thank you. I have just started materials at college, I am dong one of the assignments and got stuck on this part of it, it wants me to describ the structure including the atomic structure of the materials I had listed above, I was told that I have to draw an image of the atom itself, the atomic structure (he give us an example of a 3D model and did not explain it much). I would ask the teacher but is the weekend and I have completed the rest of the assignment just this last little bit but I am stuck. Again thank you for the help, saved me a great deal of time because I was going to start drawing the links I listed and describing them, luckily you saved me from doing the wrong thing, thank you

sorry I am not very good with chemistry, might have said the wrong terminology, I have been given the task to find an atomic structure for various materials one of them is tugsten but I cant seem to find it, I need a atomic structure for tugsten and also what I think is called a lattice structure, which I think is a 3d model of how the atoms combine, at first I thought it was called a molecule but I was corrected when I read an article explaning about metal atoms bonding. My question really is asking if the links I gave above are correct or incorrect, if incorrect could you please show me what it shoule look like? Thank you.

need to find a tugsten atom (bohr diagram) and a crystal structure (lattice structure) I cant find any anywhere, I have asked for help but know one knows....I have found these but I dont know if they are correct or incorrect: Bohr diagram: http://www.chemicalelements.com/bohr/b0074.gif Lattice Structure: I have fund 2 different ones I dont know which is correct: http://cst-www.nrl.navy.mil/lattice/struk.picts/a2.s.png Or http://cst-www.nrl.navy.mil/lattice/struk.picts/bh.s.png

I cant find any images of an atomic structure and molecules or lattice structures for the following: Tugsten Polyethelene Silicon Carbide Quartz Crystal Glass Fibre Reinforced Plastic Shape Memory Polymer If you have any links to where I could find a suitable image for any of these please tell me. Thank you. PS. sorry I am not very good with chemistry I am a mechanical engineering student and am studying materials so thats why I need to know. Done some research more and found these, can you correct me if I am wrong please, I am not very good at chemistry. Tungsten Bohr Diagram: http://www.chemicalelements.com/bohr/b0074.gif Lattice Structure: http://cst-www.nrl.navy.mil/lattice/struk.picts/bh.s.png Polyethylene: Bohr Diagram: http://www.chelationtherapyonline.com/technical/images/b0030.gif not sure about this one Lattice Structure: http://www.ndt-ed.org/EducationResources/CommunityCollege/Materials/Graphics/PolyethyleneChain.jpg Silicon Carbide: Bohr Diagram: http://mrsljones.wikispaces.com/file/view/silicon_bohr_model.jpg/290396601/132x131/silicon_bohr_model.jpg this had many different bohr diagrams so I am not sure about this one to, it says silicon, is silicon carbide different? Lattice Structure:http://www.iucr.org/__data/assets/image/0018/13239/img43.gif Not to sure about this one either. Glass fibre reinforced plastic: Bohr Diagram: cant find anything Lattice Structue: cant find anything Quartz Crystal: Bohr Diagram: cant find anything Lattice Structure:http://cst-www.nrl.navy.mil/lattice/struk.picts/sio2a.s.png Shape Memory Polymer: Bohr Diagram:cant find anything Lattice Structure:cant find anything That is all I could find but I am not sure even if the stuf I have found is correct or not, please look at it and tell me. Thank you.
