A new element, setonium, has been isolated and, consistent with some predictions, is nonradioactive. While only nanogram amounts are available, spectroscopic analysis (X-ray photoelectron spectroscopy, etc.) suggests that setonium is in the same family as chromium and will share many of its chemical properties, including most common oxidation state. Preliminary analysis suggests that the air stable form of setonium has a radius of 130 pm. Predict the formula of the form (cation, anion or oxide) in which it would likely be found in a beaker of pH 5.5 to 7 water.
