WebJul 4, 2024 · The elements of group 18 all have closed-shell valence electron configurations, either ns 2 np 6 or 1s 2 for He. Consistent with periodic trends in atomic properties, these elements have high ionization energies that decrease smoothly down the group. From their electron affinities, the data in Table 21.6. 1 indicate that the noble … WebSep 15, 2010 · The Noble Gases are the most stable because they have a full octet *and* a net charge of 0. So they're basically willing to take on a charge if it means they can have …

WebSep 16, 2024 · Summary. The electron affinity ( EA) of an element is the energy change that occurs when an electron is added to a gaseous atom to give an anion. In general, elements with the most negative electron affinities (the highest affinity for an added electron) are those with the smallest size and highest ionization energies and are … WebJan 30, 2024 · The noble gases rarely form compounds. They have the most stable configuration (full octet, no charge), so they have no reason to react and change their configuration. ... In that case, both would have the electron configurations of noble gasses, with a full valence shell. However, their charges would be much higher. It would … domestic boiler upgrade scheme
