Write the orbital diagram for the ground-state valence electrons of the main-group atom in Period 5 that has the smallest radius. Explain how you got this answer. Explain the trend in atomic radius of elements across period 3. How exactly how to use an orbital d...
Though arsenic compounds were mined by the early Greek, Chinese and Egyptian civilizations, it is believed that the element itself was first identified by Magnus who stated that it has a metal-like nature. In the book De Mineralibus, he described how the metalloid could be produced by heating...
Arsenate (As(V)) has an empty outer electron shell, missing five valence electrons ([Ar]3d104s04p0). Phosphorus (P) also belongs to periodic group 15, and, like As(V), P predominantly occurs as oxidation state five plus species in the environment, with an electron configuration of [Ne...

Further, amongst its inorganic forms, As(III) is more soluble and 60 times more toxic and mobile than As(V), as the former has been shown to react with sulfhydryl (–SH) groups of proteins and enzymes, culminating inhibition in cellular function and eventually cell death [21–26]. ...
