All halogens or group 17 elements.
any time there are as many electrons and protons and they fill each orbital optimally.
They all have a full set of valence electrons.
The electron configurations of LiF will be the same as the electron configurations of atoms in Group 18 (noble gases) because Li will lose its single electron to attain a stable octet similar to the noble gases, while F will gain an electron to achieve a complete valence shell.
None of the noble gases have 5 sublevels. All noble gases have electron configurations that end in an s or p sublevel.
socks answer should be D
The valence electron shell of noble gases is full.
the elections with the highest energy are in an f sub level. your welcome :))
The group attains electron configuration of noble gases by gaining one electron is the halogens. They have seven valence electrons and need one more electron to complete their outer shell, resulting in a full valence shell like the noble gases.
Electron affinity values for noble gases are endothermic because these elements have stable electron configurations and do not readily accept additional electrons. This makes it energetically unfavorable for them to gain an extra electron, resulting in a positive electron affinity value.
Noble gases have completely filled orbitals, are stable and chemically inert (non-reactive). So generally they will not form compounds.
Noble gases have completely filled orbitals / electron energy shells. They are stable and chemically inert (non-reactive). So generally they will not accept / gain / share electrons and they do not form compounds.
All group 18 noble gases have a completely filled outer electron shell, which gives them stability and inertness. Their electron configurations end in s2p6, meaning they have a full s orbital and a full p orbital in their outermost shell.
