Draw your electrons. You can do this a couple different ways. Some people just draw circles on the rings and fill them in. In this case, you would draw 2 on the first ring and 4 on the second ring. You can also indicate electrons by drawing X's. The best way to draw electrons is to draw them as circles with minus signs inside. This indicates not only that they are electrons, but helps remind the viewer that electrons contain a negative charge.

Draw your protons and neutrons. Erase the "C" in the center circle, and draw in your protons. Since protons are the same as the amount of electrons, you just draw 6 protons. To indicate they are protons, draw them as circles with plus signs contained inside. Neutrons are simply equal to the atomic mass minus the number of protons. Again, you'll need to do some quick math. The atomic mass of carbon is 12, and you have 6 protons. That means you need to draw 6 neutrons in your nucleus. Do not give them an indication of charge, as neutrons are of neutral charge.

Label your diagram if you want. It should be clear from your drawing which element is being indicated, but it can never hurt to clarify.
