Web5 apr. 2024 · Hence the ionic charge of Selenium (Se) is 2-. Note: The blank area shown in the above periodic table are mostly the transition and post-transition elements. They show variable ionic charge. Hence we cannot find their ionic charge by simply looking at the periodic table. In order to find the charge of these elements, we need to look at what it ... Web21 mrt. 2024 · The name of a monatomic anion consists of the stem of the element name, the suffix - ide, and then the word ion. Thus, as we have already seen, Cl − is “chlor-” + “-ide ion,” or the chloride ion. Similarly, O 2− is the oxide ion, Se 2− is the selenide ion, and so forth. Table 3.4. 2 lists the names of some common monatomic ions.
