argon and S2- are isoelectronic
Yes, S^2- is isoelectronic with Ar (argon) since both have 18 electrons and the same electron configuration.
[Ne] 3s2 3p4
[He] 2s2 2p2 (the 2's to the right of each letter mean squared)
Be3+ has only 2 valence electron and not 8.
The nearest noble gas with an atomic number lower than sulfur (S) is neon (Ne) with an atomic number of 10.
no S is not a noble gas inorder to become a noble gas u need to have a completely filled outermost shell
Yes, S^2- is isoelectronic with Ar (argon) since both have 18 electrons and the same electron configuration.
He Helium is a noble gas
[Ne] 3s2 3p4
[He] 2s2 2p2 (the 2's to the right of each letter mean squared)
Be3+ has only 2 valence electron and not 8.
Noble gases
P 3- is the ion with the noble gas configuration.
Sulfur atoms will gain two electrons in order to achieve a noble gas electron configuration. A sulfide ion has the formula S2-.
The nearest noble gas with an atomic number lower than sulfur (S) is neon (Ne) with an atomic number of 10.
Cl & K ions are isoelectronic with Ar.
In full starting with 1s and through each level. The noble gas form, where only the electrons above the highest noble gas configuration are shown, the noble gas is in square brackets. Example chlorine 1s2, 2s2, 2p6, 3s2, 3p5 [Ne]) 3s2 3p5
