The electronic configuration for the sodium ion, Na+ is
1s2 2s2 2p6 or [Ne]
neon only because sodium loses an electron an its outer shell becomes empty making its configuration the same as neon and fluorine gains an electron making its configuration the same as neon as well.
We use electron configuration for atoms or ions. You can't use it for compounds.
An electron configuration refers to the distribution of electrons in orbitals. Since there are no ions given for this question, an electron configuration cannot be provided.
neon!
The ions of elements nitrogen (N3-), oxygen (O2-), and fluorine (F-) will have the same electron configuration as a sodium ion (Na+), which is the same as the electron configuration of the noble gas neon.
In NaF, there exists Na+ and F- ions and with the electron configuration of [He]2s22p6 (for Na+) and [He]2s22p6 (for F-)
In NaCl, there exists Na+ and Cl- ions and with the electron configuration of [He]2s22p6 (for Na+) and [Ne]3s23p6 (for Cl-)
Sodium has 1 electron to "donate" and chlorine has space to "accept" 1 electron, so this electron transfer occurs and both have a stable octet electron configuration
Noble Gas
neon only because sodium loses an electron an its outer shell becomes empty making its configuration the same as neon and fluorine gains an electron making its configuration the same as neon as well.
We use electron configuration for atoms or ions. You can't use it for compounds.
metals lose electrons to form ions so as to obtain noble gas configuration. for e.g. sodium(Na) has 11 electrons i.e. 1 electron in its valent (last) shell, to attain noble gas configuration sodium loses 1 electron which may be gained by a non-metal to stabilize itself.
The abbreviated electron configuration of sodium is [Ne]3s1.

neon only because sodium loses an electron an its outer shell becomes empty making its configuration the same as neon and fluorine gains an electron making its configuration the same as neon as well.
neon!
Because each of them can form a cation with the electron configuration of a noble gas by donating one electron to another element.
