When writing the chemical formula for an ion, its net charge is written in superscript immediately after the chemical structure for the molecule/atom. The net charge is written with the magnitude before the sign; that is, a doubly charged cation is indicated as 2+ instead of +2. However, the magnitude of the charge is omitted for singly charged molecules/atoms; for example, the sodium cation is indicated as Na and not Na .

WebWhen a metal and a nonmetal exchange electrons to make a cation and an anion, respectively, they can form an ionic compound. The formula of an ionic compound indicates the kinds and number of ions. The number of anions and cations create a compound with an overall charge of zero; in other words, the positive and negative charges are balanced. WebOct 21, 2024 · The double hydrogen anion H−− does not exist as a stable species. (It occurs as a resonance, with a lifetime of 23 ns though.) If you tried to add another electron to a H− ion, the repulsion from the two core 1s electrons would be greater than the attraction due to the nucleus. The result is that there is no bound 2s energy level. sources de stress au travail
