This is a chart of the most common charges for atoms of the chemical elements. You can use this chart to predict whether or not an atom can bond with another atom.The charge on an atom is related to its valence electrons or oxidation state.An atom of an element is most stable when its outer electron shell is completely filled or half-filled.

The mean ± SD of lead, arsenic, and thallium concentrations was 3.77 ± 2.22, 8.50 ± 4.34, and 4.22 ± 2.69 μg/L. The mean levels of blood for lead, arsenic, and urinary thallium in hookah users are significantly higher than the control group ( p < 0.05). The most frequent clinical symptoms in hookah smokers were constipation and fatigue.
