Arsenic: symbol As; at. wt. 74.91; at. no. 33; valence states 3 and 5 and classified as a metalloid. has no detectable odor.

Some of its compounds do have a very weak odor ... so weak that I cannot detect them myself but have been told they are there.

Arsenic and all of its compounds are VERY Toxic.

One of the symptoms of arsenic poisonous is an odor of garlic on the breath. This I can smell.
