Toxicology Profile; Arsenic Basic Chemistry Introduction Arsenic is an abundant naturally occurring element with an atomic number of 33 and an atomic weight of 74.92 g. Although strictly a metalloid, arsenic is commonly referred to as a ‘heavy metal’ and can be found within group 4 of the periodic table.

the same valence electron because of their location and family relation to the period table. The alkaline metals are a reactive group of metals and combine with other elements so easily that they are not found on earth in the form of their free metal.

College students have financial obligations outside of the classroom; being on scholarship does not lighten the…
