Sodium can become stable by losing 1 electron, forming a sodium ion with a 1+ charge, with the formula Na+. By losing its single valence electron, the resulting sodium ion achieves the noble gas configuration of neon, so that it has an octet (8) of valence electrons.
When chlorine gain an electron become the anion Cl-.
negatively
when sodium valence electron is transferred to chlorine , both atoms become ions . the sodium atom becomes a positive ion . the chlorine atom becomes a negative ion .
An atom of Calcium will lose an electron to become a posotive ion.
negatively
Farogen is not an elemnt known to science. The element that can use one electron is chlorine, which achieves the octete when it gains an electron. hydrogen becomes the hydride ion with a stabel duet (He configutaration) Sodium can lose one electron to acheive the octet.
A chlorine atom needs one additional electron in order to become stable.
positively
When chlorine gains an electron , it forms an anion. It is represented as Cl-
positively
Calcium loses its two valence electrons to become Ca 2+ ion.
In a nitrogen atom's ground state, it has five atoms. The electron will have to gain three electrons to become stable.
When chlorine gain an electron become the anion Cl-.
It gains one electron to become Cl^-.
A negatively charged "ion".
negatively
when sodium valence electron is transferred to chlorine , both atoms become ions . the sodium atom becomes a positive ion . the chlorine atom becomes a negative ion .
