Electronic configuration of beryllium: 1s2.2s2.
three dimensional arrangement of atoms electron-group geometry
2,4.
Oxygen.
electron configuration :)
Electronic configuration of beryllium: 1s2.2s2.
The normal electron arrangement of sodium(Na) in K, L and M shells is 2, 8, 1 and the electronic configuration of the metal in its sub-shells is 1s2 2s2 2p6 3s1.
The electron shell arrangement of Ceasium is 2.8.8.18.18.1
Sulphur. Please see the link.

Potassium: - Electronic configuration: [Ar]4s1 - Electrons per shell: 2,8,8,1
Since the electron arrangement is 2,8,18, and 32, the electron arrangement for a calcium atom is 2,8, and 10.
Due to small size and high electron density of oxygen compared to sulphur, interelectronic repulsion is higher in oxygen, resulting in less energy being released when an electron is added to oxygen, due to lesser stability after electron is added, which is due to the interelectronic repulsion in the small oxygen atom. Hence electron affinity value is lower. It is an abnormality and exception to the general periodic trend of electronic affinity values.
Electron group arrangment and molecular geometry is same.It is tetrahedral in shape
what does chlorine have t do to achieve the same electron arrangement as neon
Sulphur
If you mean Sulphur (s) It's 2.8.6
