A common element used in rat poison is Arsenic, although there are other components such as zinc phosphide, bromethalin, and cholecalciferon. None of the last three, however, are single elements.
As is the symbol for the element arsenic.

No, atropine is not an antidote for cyanide poisoning. The primary antidotes for cyanide include hydroxocobalamin and sodium thiosulfate. Atropine is an anticholinergic medication used to treat bradycardia and certain types of poisoning, but it does not counteract the effects of cyanide.
A rather long time ago, arsenic was used as a rodenticide. However, the dangers presented by this practice caused it's reversal. Modern rodenticides are typically compounds that work as anticoagulants.
Arsenic can be used to create arsenic trioxide, which is a commonly used poison. It is a colorless, odorless, and tasteless crystalline powder that is highly toxic. Arsenic poisoning can lead to symptoms such as vomiting, abdominal pain, and in severe cases, death.
The antidote for lead poisoning is a medication called chelation therapy. This treatment involves administering chelating agents that bind to the lead in the body and help facilitate its elimination through urine. Chelation therapy should be done under the supervision of a healthcare provider.
The answer is arsenic and this is a solid chemical element, atomic number 33 and its atomic weight is 74,921 60(2). Arsenic is a metalloid.
The cyanide antidote is nitrite, specifically amyl nitrite or sodium nitrite, which helps to convert hemoglobin to methemoglobin, allowing it to bind cyanide. 2-PAM chloride (pralidoxime) is an antidote for organophosphate poisoning. Atropine is used to treat certain types of poisoning or overdose, but not specifically for cyanide poisoning.
Historically, arsenic was used on rats. Some insecticides used thallium, a heavy metal.
There are many elements that can be used for poisoning but there is an element that has a nickname "Poisoner's Poison". That element is called Thallium it has a silvery white color this metal is so soft you can cut it with a knife at room temperature. This metal also oxidises quickly when exposed to air.
