This chemical element is neon (Ne).
There are a total of 9 electrons so that would be the element fluorine.
Iron has the electron configuration [Ar]3d64s2.
[He] 2S2 is the noble gas electron configuration for beryllium.
This shows 19 electrons, with 4s1 as a valence electron. This is potassium (K).

The element is Argon. Its configuration is 2 8 8.
Sodium has the configuration Ne 3s2 . Sodium is group-1 element.
The electron configuration of the element with the atomic number 39 (yttrium) is: [Kr]4d15s2.
The element sulfur (element number 16) has an orbital configuration of 1s2 2s2 2p6 3s2 3p4.
Beryllium would have that configuration
The element with that electron configuration is Iron.
