Web18 okt. 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 4.7. 2 lists the names of some common monatomic ions. WebTo give you the short answer: An acidic solution has a high concentration of hydrogen ions (H ^+ + ), greater than that of pure water. A basic solution has a low H ^+ + concentration, less than that of pure water. To see where this definition comes from, let’s look at the acid-base properties of water itself. Autoionization of water
Although there are nine known isotopes of helium (2He) (standard atomic weight: 4.002602(2)), only helium-3 ( He ) and helium-4 ( He ) are stable.
