Arsenic is not inert; it is a toxic element that can have harmful effects on living organisms. It is classified as a metalloid and has a variety of chemical forms, some of which are more toxic than others.
The two main types of arsenic are inorganic arsenic, which is often found in contaminated water and soil, and organic arsenic, which is commonly found in seafood. Inorganic arsenic is considered more toxic and a greater health concern than organic arsenic.
yes
The only stable, and thus by far the most common, isotope of arsenic is arsenic-75, although isotopes have existed from arsenic-60 through arsenic-92. The isotopes with the longest half-lives are arsenic-73, arsenic-74, and arsenic-76.
No, arsenic is more reactive than nitrogen. Arsenic belongs to Group 15 elements in the periodic table which are more reactive compared to nitrogen, which is a relatively inert gas.
Antimony is more metallic than arsenic. Antimony exhibits metallic properties, such as high electrical conductivity and luster, while arsenic is classified as a metalloid with properties of both metals and nonmetals.
Yes, fluorine is more reactive than arsenic. Fluorine is a highly reactive non-metal element, whereas arsenic is a metalloid that exhibits less reactivity compared to fluorine.
Antimony is more metallic than Arsenic. As we already know, metallic nature increases down a group. As Antimony lies just below Arsenic in Group 15, it is said to have more metallic character.
I suspect you're looking for arsenic as your answer, as this element is effectively toxic to mammals, including mice, rats, etc. However, it'd be the wrong answer for a few reasons. The first reason is that arsenic is no longer used as a pesticide pretty much anywhere in the world, due to its toxicity to humans, and its tendency to remain in the environment. The other reason is that, in sufficient dosage, a huge number of components of the periodic table -- elements -- are toxic to humans, and some are hyper-toxic. Polonium, for instance, (Po 210) has an LD50 (Lethal dose in 50% of the test population) of perhaps 0.1-0.3 GBq, making it far more toxic than arsenic.
H3AsO4 is stronger than H3SbO4. This is because As (arsenic) is more electronegative than Sb (antimony), leading to a more acidic nature for arsenic compared to antimony.
There are several metals that are toxic...but let's make your teacher's life exciting and put down thallium and uranium. You could also put down lead and Mercury. Arsenic is a metalloid rather than a metal.
