No element is the symbol for toxicity. The symbol of it is a skull and crossbones. A picture of it will be linked and found in related links
The element with chemical symbol As, is Arsenic. Arsenic in part of the Group 15 family of elements along with Nitrogen, Phosphorus, Antimony and Bismuth. Arsenic has 33 electrons in a standard atom, with 4 electron shells and 5 electrons in the outer shell.
TL on the periodic table is the chemical symbol for thallium. Thallium is a soft, malleable metal that is known for its toxicity. It is often used in electronics and as a component in high-temperature superconductors.
ClO4- Note that this is not an "element" and hence doesn't have an "element symbol."
The chemical symbol for the element Xenon is Xe.
Take the element "Iron" then the symbol for the element is "Fe" and "Fe" is also the symbol for a single atom of the element in a chemical equation.
