Thank you for answering my questions with a helpful suggestion. I have a couple more questions regarding the valence arrows.
My first question has to do with the blank lines over the 2p, following the valence arrows. Because in your example, you used one separation line under the sp, with one space between the valence arrows, but in the case of blank lines ... do I make two separation lines, or use a space within one separation line?
My second question has to do with the more complex display with the elipses as shown in the attachment. Apparently the elipses are pointing to the various components of the display?
Thank you for your time.
