I hope all is well with you and your family. I am doing a Chemistry book and I have a question concerning arrows in orbitals (boxes) that are being transcribed in UEB Technical. My attachment is below. Should these arrows enclosed in the orbitals (boxes) in the table be done as a tactile or am I safe doing them in braille? If doing them in braille should I use the enclosure indicator with a box or is there a more simplified way to present them to the student? Thank you so much for your time and knowledge. I look forward to your reply. Have a happy and wonderful day!
