Minimize acquisition time where possible or collect data from several different locations on the sample (with very short acquisition times) and integrate the data. Interpretation of XPS spectra As3d peak has overlapping spin-orbit components (Δ=0.7eV, intensity ratio=0.7). As LMM peaks (betwe...
Arsenic (As) lies directly below P on the periodic table and so the two elements share many chemical properties, although their chemistries are sufficiently dissimilar that As cannot directly replace P in modern biochemistry. Arsenic is toxic precisely because As and P are similar enough that ...
The team at periodicvideos has created a TED-Ed Lesson for every element of the periodic table. This one is about arsenic -- element number 33 and is famous for the toxicity of its compounds.
Arsenic, a chemical element in the nitrogen group (Group 15 [Va] of the periodic table), existing in both gray and yellow crystalline forms. Its chemical symbol is As, and it was first clearly identified as a free substance in 1649 by German pharmacist J
Arsenic poisoning occurs as a result of industrial exposure, from contaminated wine or illegally distilled spirits, or in cases of malicious intent. Read on to learn more about symptoms, treatment & safe limits.
Birds eat the fish that already contain eminent amounts of arsenic and will die as a result of arsenic poisoning as the fish is decomposed in their bodies. More information on properties of arsenic Read more on arsenic in water Information on arsenicosis Back to the periodic table of elements...

Arsenicis the 33rd element of the periodic table and is exclusively found as the monoisotopic75As. It is a semimetal with good electron conductivity due to the 4p orbital overlap[13]. An element mainly known for its toxicity employed in the production of pesticides, insecticides, herbicides, an...
Arsenic is very similar chemically to its predecessor in the Periodic Table, phosphorus. Like phosphorus, it forms colourless, odourless, crystalline oxides As2O3 and As2O5 which are hygroscopic and readily soluble in water to form acidic solutions. Arsenic(V) acid is a weak acid. Like phospho...
