how do i draw an electron-dot diagram?

This is based on the electons in the outer shell of the atom you are drawing. From the periodic table you can see how many electrons are in the outer shell e.g. Na has 1, Cl has 7, to create a complete shell (8) they combine to form NaCl. \n\nIf you wanted to draw all of the electrons then you would draw the first shell with 2, which completes the first row of the periodic table, then the second with 8, then the third with 1 (for Na). For Cl you would draw the first shell with 2, which completes the first row of the periodic table, then the second with 8, then the third with 7. \n\nIf you wanted to show the bond between them then you would draw the shells with the final circles combining and two electrons touching the circles.\n\nI did a search and found the website below, there are probably better ones out there but this gives a pictorial representation of some of what I say

It doesn't give me room to list them all and explain them on here so let me direct you to a website I found that does a pretty good job:\nhttp://vergil.chemistry.gatech.edu/notes/quantrev/node20.html

You'll have to create it yourself. Here's how, with free, legal software:\n\n1. Download Inkscape, a free vector drawing program.\n2. Run it.\n3. File Menu -> Document Preferences\n4. Set Canvas Size to your paper size (Probably US Letter in the US or A4 elsewhere)\n5. Set Default Units to mm.\n6. Close dialog\n7. Create an ellipse with the ellipse tool\n8. Select the ellipse with the selection tool\n9. Set its width to 150 mm and its height to 86.1 mm using the text entries at the top of the window.\n10. Adjust the fill and stroke of the ellipse to whatever you like\n11. Print it.

The most important thing is to learn the Electron Configurations as you learn the periodic table because it is the fundamental basis for the way that the table is configured.\n\nHere is a good Periodic table with a good explanation of Electron Configurations.\n\nhttp://www.abacusscience.com/periodictable.html\n\nhttp://www.abacusscience.com/electronconfiguration.html

lol\ni did this assignment before. i also had to research in on line because it was gong to be in my exams\n\nit really easy\n\nyou got to yahoo search engine and type microscope and click image search. you will find tons of microscope pictures from the very basic hand drawn kinds to state of the art compound electron microscope

Try Google or Yahoo.  You'll find worked examples there.  I think it needs diagrams to understand; they and the accompanying explanations are too complex to attempt to reproduce here.

Try searching for "Venn Diagram."

This is a more complicated question than it appears.  You didn't include to what degree you were seeking this information, so rather than go into a great deal of explanation I have included a link that explains and tabulates the basics of electron energy levels.  Hope this helps.

The best method to solve these type of problems is to sove them through VENN Diagrams. First draw a rectangle which is the sample space, then draw three circles intersecting each other wjich are E, F AND G. The common region between E & F is P[E n F] and so on. It is quite difficult to explain this in writing but I hope you have understood. Now by drawing Venn diagram I have tried to solve ur questions.\n\nPr[EuF'] = P[E] + P[F'] - P[E n F']\n         = 0.35 + (1 - 0.5) - (0.35 - 0.1)\n         = 0.6\n\nPr[F'nG']= 1 - P[F u G]\n         = 1 - ( P[F] + P[G] - P[F n G])\n         = 1 - ( 0.5 + 0.45 - 0.3)\n         = 0.35\n\nPr[E'nG] = P[G] - P[E n G] = 0.45 - 0.2 = 0.25\n\nI think above answers are correct and hope they help you!!

I tried to draw you one in MS Paint, but it didn't turn out too good... go here instead\nhttp://www.beyondlogic.org/keyboard/keybrd.htm

There is a free version of diagramming software, called "Dia" which is hosted on SourceForge.  If you are using Windows, they do have a Windows download as well.  The site contains the download links, FAQ and documentation if needed.\n\nAlternatively, there is another package (which has a free trial, but is commercial) called "SmartDraw", which can also be used if you only need to temporarily create diagrams.\n\nI've included the links to both below.

The nucleus is easy to model you just need little balls to represent the neutrons and protons. The click it magnetic balls spray painted to represent protons and neutrons may work, otherwise buy little round balls and spray paint them.\n\nYou have a few options when you are modeling the electrons orbiting the nucleus you can either string beads on wires to represent the number of electrons (the planetary model). Or string the electrons in the Bohr model.\n\nIf you are going to be more accurate you need to put the electrons in the electron shells. \n\nYou could make the shell shapes out of wire http://www.steve.gb.com/science/atomic_structure.html and string in the right number of bead electrons or you can try and make plastic representations of the shells and paint the electrons on the shell.\n\nThere are kits at indigo.com that represent the electron shell shapes, those may be worth buying

choose the noble gas that comes before the element.   in Mn(2+)'s case, that's Ar\n\nwrite the noble gas down in brackets, and continue on with the electron config. as normal\n\n[Ar}4s23d3\n\nFor O(2-), it turns into Neon so it would just be [Ne]
