Because of the high reactivity of the metal, toxicological data are available only for compounds. Soluble barium compounds are poisonous. In low doses, barium ions act as a muscle stimulant, and higher doses affect the nervous system, causing cardiac irregularities, tremors, weakness, anxiety, shortness of breath, and paralysis. This toxicity may be caused by Ba blocking potassium ion channels, which are critical to the proper function of the nervous system. Other organs dam… 웹We compared the atomic radii of the metal ions that support the HutP–RNA interactions in order to study the pocket that accommodates the metal ions. When we compared the ionic radii of the metal ions, based on their preferred hexameric coordination, we found that the radii for Cu 2+, Mg 2+, and Co 2+ were nearly the same size (Table 4).

"Hydration number-Number of water molecules forming a stoichiometric complex with the ion (e.g. [Be (H2O)4]2+). The hydration number gives the number of water molecules in the primary shell, though the total number of water molecules affected can be much larger and depends on the method of measurement."
