Notes:
Arsenic is found in both the yellow and gray crystalline forms.
Gray arsenic is very brittle and tarnishes in the air. It sublimes
under high heat. Because arsenic is highly toxic, it makes a good
weed killer and insecticide. The radioactive isotopes have been
used in medical diagnostic procedures.
