WebJan 27, 2013 · What ions does not have a noble gas electron configuration S-2 Sr 2 I- Cs or Be 3? Cs does not have a nobel gas electron configuration, as it contains one valence electron in its outermost s orbital. Be3+ also does have a nobel gas electron configuration, as this occurs when Be has a 2+ charge (the typical Be ion is Be2+). WebCs - 46: Po - 174: At - 270: Rn + 68: The halogens (group 17 elements) have highly negative electron gain enthalpies as they can reach the stable noble gas electronic configuration by taking an electron. ... Halogens have a highly negative electron gain enthalpy because they show a strong affinity to reach stable noble gas configuration.

WebThe condensed EC is expressed by writing the nearest noble gas in square brackets and the remaining configuration of valence electrons is depicted following that. The closest noble gas to Ag is krypton (Kr). It can accommodate 38 electrons. The remaining 11 electrons in Ag are present as valence electrons. WebAboutTranscript. To find the electron configuration for an ion, first identify the configuration for the neutral atom. Then, add or remove electrons depending on the ion's charge. For example, to find the configuration for the lithium ion (Li⁺), start with neutral lithium (1s²2s¹). Then, since the lithium ion has one less electron, remove ... points 2 home saskatoon
