Arsenic (As) is not an essential element for the human body. (a) Based on its position in the periodic table, suggest a reason for its toxicity. (b) When arsenic enters a person's body, it quickly shows up in the follicle of the growing hair. This action has enabled detectives to solve many murder mysteries by analyzing a victim's hair. Where else might one look for the accumulation of the element if arsenic poisoning is suspected?

a. Arsenic and Phosphorous share similar chemical properties as they are present in the same group. So arsenic replace phosphorous(P) in molecules like ATP which are main energy sources for body. It disrupts the celluar processes that produces ATP due to which other cells in the human body do not get energy due to which the cells die.b. One can also look for accumulation of arsenic poisoning in nails and bones as trace amounts of arsenic will be settled in there as well.
Periodic Relationships Among the Elements
Periodic Table properties
University of Toronto
In chemistry and physics, a periodic table or periodic chart is a tabular arrangement of the chemical elements, ordered by their atomic number, electron configurations, and recurring chemical properties. Elements are presented in order of increasing atomic number ("column") and periodic properties, such as symbol, name, atomic mass and group (period) number are listed for each element. The periodic table can be used to derive relationships between the various properties of the elements, and predict the properties of new elements yet to be discovered or synthesized.
The periodic table is a tabular display of the chemical elements, organized on the basis of their atomic numbers, electron configurations, and recurring chemical properties. The table can be used to derive relationships between the properties of the elements, and predict the properties of new elements yet to be discovered or synthesized. The periodic table can be used to summarize chemical behavior, and it is widely used in chemistry and other sciences as a tool to determine the chemistry of new substances.
