What noble gas has the same electron arrangement as Sr2?

Krypton has the same electron arrangement as Sr2. Both have a total of 36 electrons arranged in outer shells with the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6.


What -2 charge ion has same electron configuration as krypton?

The -2 charge ion with the same electron configuration as krypton is the oxide ion (O2-). Krypton has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6. The oxide ion gains two electrons to achieve a full valence shell, resulting in an electron configuration of 1s2 2s2 2p6.


How many electrons will Strontium gain or lose in forming a noble gas configuration?

Strontium, a group 2 element, will lose 2 electrons to attain a noble gas configuration because it will achieve a stable electron configuration similar to the nearest noble gas, which is krypton. Strontium has 38 electrons in its neutral state, while krypton has 36 electrons. By losing 2 electrons, Strontium becomes Sr2+, and its electron configuration is similar to krypton.
