Maybe this wil lhelp.         \n\n ELECTRON DOT DIAGRAMS\n1. Let the element's SYMBOL represent the nucleus and inner energy level .\n2. Write the ELECTRON CONFIGURATION for the element (or look at the PERIODIC table).  Count the electrons in the OUTER energy level.\n3. Let the top, bottom, and two sides represent the ORBITALS.\nPlace the appropriate number of DOTS in each "orbital".\nUse ONE dot if the orbital has 1 electron and TWO dots if the orbital has 2 electrons.  The electron dot diagrams for:\n \nNa(Z=11)  1s2   2s2   2p6  3s1       Na\n \nMg(Z=12)  1s2   2s2   2p6  3s2             Mg\n \nAs(Z=33)  1s2   2s2   2p6  3s2  3p6  4s2  3d10  4p3      As\n \nThe periodic table can also be used to write electron dot diagrams.\nAll the elements in the first column have ONE outer electron(s).  They have ONE dot(s) in their electron dot diagram. All of the elements in column 2 have TWO outer electrons.  They have TWO dots in their electron dot diagram.  Most of the elements in column 18 have EIGHT outer electrons except HELIUM which only has TWO outer electrons.  All of the elements in column 18 have EIGHT dots in their electron dot diagram except HELIUM  which only has TWO.

Here are a couple sites that might help. I could not find any diagrams though. Good luck!

(NH4)2Cr2O7 -> Cr2O3 + 4*(H2O) + N2\n\n(NH4)2SO4 + 2*(NaOH) -> 2*(NH3) + 2*(H2O) + Na2SO4\n\nFe2(SO4)3 + 6*(NH3) + 6*(H2O) -> 2*(Fe(OH)3) + 3*((NH4)2SO4)

Chromium dioxide or chromium(IV) oxide is a synthetic magnetic substance once widely used in magnetic tape. With the increasing popularity of CDs and DVDs, the use of chromium(IV) oxide has declined. However, it is still used in data tape applications for enterprise-class storage systems. It is still considered today by many oxide and tape manufacturers to have been the most perfect magnetic recording particulate ever invented.\n\nChromium(III) oxide doesn't have any industrial significance.

Doing the Lewis dot structure for lead is a little hard here since I can not necessarily draw the structure on the screen, but here is how to do it.\n\nFirst, take out your periodic table and see where Pb, lead, is located.  Then, determine how many s and p electrons you have, do not count the center electrons is basically what you do, meaning it has 4 outer electrons.  Thus, draw 4 dots around Pb, and you have a Lewis dot structure.

here's a site that has the most basic symbols:  http://www.csgnorth.com/lowes/archsym.htm\n\nADDED: Plumbing and electrical are also on there (additional links on the top).  This site is also useful, although it has pop-up's:   http://www.bhg.com/bhg/story.jhtml?storyid=%2Ftemplatedata%2Fbhg%2Fstory%2Fdata%2F15233.xml

8 dots around each element. this is a salt, so is realtively stable. hope that helps!

K2Cr2O7\nPostassium ion: K+\nDichromate ion: Cr2O72(2-)\nso to there has to be 2 potassium ions for each dichromate ions. You can also see http://en.wikipedia.org/wiki/Potassium_dichromate\nif you want more info.
