    I don't usually get called upon to do science, and was given a test in Physical Science class that seems to use a lot of chemistry. So, here are two questions:

    1. Does this arrangement of Louis dots look right to you as I have transcribed what was in print? I had never even heard of Louis dots before yesterday. (I hope my simbraille comes out well enough for you to see). Do I put these on a special symbols page? Do I need box lines around them?

    2. This test does seem to have quite a bit of chemistry, but some questions are just more physical science in nature. So, can I do just the chemistry related questions using the chemistry code, and the rest of the questions in regular nemeth? Reason I am asking is some of the just plain science questions have abbreviations, such as km., cm., and I am not sure as to whether I have to punctuate the entire test using chemistry code rules for sections that don't seem to require them.

    Thank you so much for any help!!

    Hi Susan. Your transcription of the four electron dot configurations is exactly correct. Isn't it nice how simple they are? It's not clear to me in your simbraille example if you have the same number of blank cells between each atom. Three blank cells is standard. No, you do not need to show the box lines around them. Yes, you should list the two bonds on a Special Symbols page. Use the heading "Electron Dots" and use the same description as you find on page 12 of the Chemistry Code.

    I am guessing that the chemistry questions are scattered around the test, not all grouped together? If so, it is best to use the same code throughout the test. Including punctuation indicators with all scientific abbreviations will not hinder the reading in any way. State on a Transcriber's Notes page that all material on the test is brailled following the rules of the Braille Code For Chemical Notation 1997.

    If, instead, all the chemistry questions are grouped together, you can insert a transcriber's note at that point stating that the rules of the Braille Code For Chemical Notation 1997 are used for questions # - #.

    Thank you for your question.
