An electron dot diagram is a method of writing the chemical symbol of an element by surrounding it with dots to indicate the number of valence electrons. Valence electrons are found in an atom's outer shell and are the ones involved in chemical reactions.
Drag the shape representing the element you want to add to a diagram from the stencil onto the drawing page. For many shapes, such as Class shapes, Use Case shapes, and Component shapes, an icon representing the new element appears in the tree view. Tip: You can also add an element to a diagram by creating a new element in the tree view, and then dragging the element onto the drawing page.
