Sodium is in the third group in the periodic table. It meens that sodium has three shell. First shell - 2 electrons, second shell - 8 electrons, third shell (outer energy level) - 1 electron.
None - the electron goes from sodium TO the chlorine.
Sodium has one electron in its outer shell, so it tends to lose that electron to achieve a full outer shell. This makes sodium more stable as it follows the octet rule by having a complete outer electron shell with eight electrons.
No, sodium's outer shell is not stable because it only has one electron in its outer shell. Sodium will readily react with other elements to achieve a stable electron configuration by losing this electron.
One chlorine atom has 7 electrons in its outer shell, and sodium has 1 electron in its outer shell. Therefore, sodium can donate its electron to chlorine, forming a stable compound where chlorine has a full outer shell with 8 electrons.
Sodium does not have a full outer valence shell. It has one electron in its outermost shell, which makes it very reactive and likely to lose that electron to achieve stability.
Lithium and potassium are both alkali metals. Thus their outermost orbitals are filled up to s1. So, that shows us that they both have only one outer level electron each.
1 Its electron configuration is 1s22s22p63s1. A good periodic table that includes electron configurations can be found under related links.
Sodium has one electron in its outer ring.
Sodium has 1 electron in its outer shell, and it needs to lose that one electron to achieve a full outer shell (valence shell) with 8 electrons. By losing this one electron, sodium will achieve a stable electron configuration similar to that of the noble gas neon.
The nucleus of sodium has a greater pull on the electron in the outer shell compared to the nucleus of neon. This is because sodium has one less electron in its outer shell than neon, resulting in a stronger attraction between the nucleus and the remaining electron in sodium.
Bromine has 7 electrons in its outer shell and needs to gain one electron to have a full outer shell and become an ion. It will gain this electron from an atom that has one electron in its outer shell such as Lithium or Sodium.
