Every halogen has the capacity to accept one electron from a sodium atom and to thereby achieve a noble gas electron configuration of eight valance electrons. The halogens are fluorine, chlorine, bromine, iodine, and astatine.
Sodium has the configuration Ne 3s2 . Sodium is group-1 element.
Sodium is atomic number 11 so it has 11 electrons. The electronic configuration would be 1s2 2s2 2p6 3s1.
Sodium has the configuration Ne 3s2 . Sodium is group-1 element.
When fluorine (F) takes an electron from sodium (or from any element in an ionic bonding scenario), the 2p6 sub-orbital is filled, which allows fluorine to achieve the electron configuration of nearby neon (Ne).
The noble gas (electron) configuration is a scheme for writing the electron configurations of elements in a kind of "shorthand" so it is easier to write them. For potassium element - not ion , [Ar] 4s1 is the way it is written in noble gas configuration. If we could not use this shorthand and had to write out the electron configuration completely, it would like this:1s2 2s2 2p6 3s2 3p6 4s1Wikipedia has other information on potassium, and a link is provided.For Sodium it is [Ne]3s1 and thus for sodium ion it is just [Ne]
Chlorine (Cl)
fluoride
neon!
Sodium fluoride has electron and ionic elements. This is taught in science.
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.
Atoms of the element sodium (atomic number 11) have the electron configuration 1s22s22p63s1 with the noble gas form [Ne] 3s1
Sulfur
An iron atom is a different element than a sodium atom because it has a different ground state electron configuration. In fact, any atom that differs from any other atom in ground state electron configuration is a different element.
The electronic configuration of sodium is [Ne]3s1. Sodium has one valence electron. And it belongs to group 1. The valence electron is in 3s orbitals and it tells that sodium is a s-block element and is in period 3.
Sodium.
neon
With it being a dipositive ion, the original element has lost 2 electrons. Making the configuration 1s2 2s2 2p6 3s2 2p4. That Configuration is Sulfur.
