The sodium atom (atomic number 11), with 1 valence electron in its third energy level, would like to achieve the stability of its nearest noble gas neighbor, the neon (Ne) atom (atomic number 10), which contains 8 valence electrons in its second energy level.
Why does the sodium ion have at 1 charge? Sodium is in group 1, meaning it has only one valence electron. In compounds (ionic) it has given off this electron to a nonmetal element (oxygen, chlorine), so it becomes cha â¦ rged +1.
