Imagine a square. In an electron dot diagram, the elements symbol is in the center. It represents the nucleus and the inner electrons. The valence electrons are drawn as dots on the sides of the square. These electrons are distributed one on each side, and then paired up. For example, chlorine is in period 17 and has 7 valence electrons. "Cl" would go in the center of the square, and then there would would be two dots on three of the square's sides, and one dot on the other. However, the sides of the square are imaginary, don't draw them.
