Periodic Table/ Elements toxic to one another?
So Arsenic is poisonous to Oxygen based life forms (Humans). What would be poisonous to a Sulfur based life form (if they exsisted)?

There are metallotolerant bacteria, which can tolerate relatively high levels of As and other heavy metals.
Toxicity is a term with respect to life forms. Elements are not toxic to one another.

If you look on the periodic table, Arsenic is right below Phosphorous in Group V A. Dmitri Mendeleev, a Russian physicist in the 1800s, proved that elements in the same groups have similar chemical properties. Arsenic is so similar to Phosphorous that arsenic can bind to several enzymes that catalyze reactions of phosphorous-containing compounds in our body and inhibit them, leading to a loss of function and eventual cell death.
