A neutral sodium must lose one electron in order for the resulting sodium ion to have the same electron configuration as an atom of the element neon.
The ground-state electron configuration for a neutral atom of manganese is: 1s22s22p63s23p63d54s2 or [Ar]3d54s2
The electron configuration of arsenic is: [Ar]4s23d104p3.
Calcium has the electron configuration [Ar]4s2; the neutral atom of calcium has 20 electrons.
First, we need to add up the number of electrons in the configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10. Doing so gives a result of 30. A neutral element having 30 electrons will also have 30 protons. Checking the periodic table, we see that zinc is the element with 30 protons.
It is the electron configuration of a neutral, not excited atom.
Yes, but an electron configuration could be that of an ion. The identification of an element depends on the number of protons in its nucleus, so only when the species is also neutral can the electron configuration be used to identify it. Examples 1s2 2s2 2p6 is the electron configuration of Neon but also of F-. Take the superscripts and add them together to get the atomic number and if neutral must be Neon but if negative is that of F-
The electron configuration for neutral Chlorine is 2.8.6.
A neutral sodium must lose one electron in order for the resulting sodium ion to have the same electron configuration as an atom of the element neon.

The electron configuration of beryllium is written as [He] 2s2. This means that it has 2s2 electrons above the configuration of Helium.
The neutral configuration is [Ne]3s23px1 or 1s2 2s22p6 2p1 3s23px1
