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.

Silicon has 4 electrons in its outer shell.
Sodium has one electron in its outer ring.
The outer shell (N=4) of the copper element has 2 electrons.
Two electrons are needed to fill the outer shell of a sodium atom. The outer shell for sodium is the 3s sublevel. A neutral sodium atom has one electron in its 3s sublevel. Since atoms undergo chemical bonding in order to gain a noble gas electron configuration, called an octet, sodium atoms will lose their single 3s electron, becoming sodium atoms with a 1+ charge. By doing this, sodium ions become isoelectric with the noble gas neon, and achieve an octet, becoming stable.
None - the electron goes from sodium TO the chlorine.
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 has ONE valence electron in its outer shell that is to be donated to any kind of oxidant. By then the outer (3rd) shell (of the Na+ ion) is EMPTY, so the 2nd shell has become the outmost, containing 8 electrons (Ne-configuration). No electrons at all are taken up by sodium.
Just one.
Nitrogen has five electrons in its outer shell and bromine has seven in its outer shell.
Boron has three electrons in its outer shell
Vanadium has on the outer shell two electrons.
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.
Calcium has two electrons in the outer shell.
There is one electron on cobalts outer shell.
