two chlorine atoms
Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.
What symbol would represent a chlorine ion that has ionized to have a stable electron configuration?
Cl - This means that Chlorine has an extra electron, so it's negative. Chlorine already has 7 electrons and in order to be stable, it only needs one more electron.
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
Generally, atoms would want to fulfill the octet rule: 8 electrons in the valence shell. This gives the atom a noble gas configuration and is seen as stable. Since the Chlorine atom is in group 7 of the periodic table, it "prefers" to gain one electron instead of losing 7 to attain the stable octet configuration.
if lithium loses one electron it attains the stable noble gas electron configuration of helium. hence it is highly reactive.
Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration. Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability.

Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.
The group of elements that have a stable electron configuration are the noble gases.
Atoms gain stable configuration of noble gas, by either gaining or losing (as in ionic compounds) or sharing electrons (as in covalent compounds).
What symbol would represent a chlorine ion that has ionized to have a stable electron configuration?
They achieve stable configuration by sharing their electrons in their outermost shell.
Oxygen atoms need to share or gain two electrons in order to achieve a stable electron configuration.
The electron configuration of copper is: [Ar]4s13d10. It isn't 4s23d9 because Cu is able to obtain a more stable electron configuration when it takes an electron from the 4s and adds it to 3d. A half filled 4s and a completely filled 3d is more stable.
A stable electron configuration.
