Where Can i find drawing of the electron dot structure of the following atoms.
www.webelements.com will give you the electron configuration. Scroll down the menu on the left side. The electron dot structure is done this way:
Write the symbol for the element. That stands for the nucleus and all of the inner shell electrons. Add a dot to represent each electron in the outside shell.
For example, Na in in group IA; therefore, it has 1 electron in its outside shell. The electron dot structure is Na.
Ca is in group IIA; the electron dot structure is Ca:
Mg is Mg:
It is harder to do Cl (because I can't put in the spaces but here is a try).
It works a little better in bold face.
Well, Ca would just have two (assuming it's in group 2, I don't have a periodic table handy), and Iodine is diatomic, so just stick the two of them together!
