The electron configuration of sodium is: [Ne]3s1.
Na is an s-block element, in group 1, period 3 and it has 11 electrons. Thus, the configuration is
1s2 2s2 2p6 3s1
Na has one valence electron i.e. 1 electron in valence(last) shell.
When a Na atom loses one electron, it becomes a Na+ ion and gets a charge of +1.
The ionic radius of Na+ is smaller than F- because, when sodium loses an electron to form Na+, it loses an electron in a higher energy level, resulting in a smaller radius. Conversely, when fluorine gains an electron to form F-, it fills its valence shell, resulting in a larger radius due to electron-electron repulsion.
The element with this electron distribution is sulfur (S). The electron configuration 1s^2 2s^2 2p^6 3s^2 3p^4 corresponds to the atomic number 16, which is sulfur.
In sodium, the ion formed is Na+ (sodium cation). Sodium typically loses one electron to achieve a stable electron configuration.
Electron configuration for an atom is the distribution of electrons on atomic orbitals.
The element with this electron distribution is sulfur (S). The electron configuration 1s^2 2s^2 2p^6 3s^2 3p^4 corresponds to the atomic number 16, which is sulfur.
A new ionic species - Na- (it does not exist) Perhaps you meant the loss of an electron? In this case, sodium readily loses an electron to form Na+.

Sodium loses one electron, therefore Na+ Chlorine gains an electron, therefore Cl-
The noble gas electron configuration of sodium fluoride is [Ne]3s^1 3p^5. This means that it has the same electron configuration as neon, with an additional 3s^1 electron from sodium and a 3p^5 electron from fluorine.
Neon has the same electron configuration as Na+ ion
remove an electron. Na = Na+ + e-
The electron-dot structure of sodium atom is 'Na-dot' or 'Na.' One dot is one valence electron.
In NaCl, there exists Na+ and Cl- ions and with the electron configuration of [He]2s22p6 (for Na+) and [Ne]3s23p6 (for Cl-)
The electron distribution differs between energy levels. In this case, levels one and four have 2 electrons, level 2 has eight, and level 3 has thirteen.
This sodium ion is denoted by: Na+
