Sodium has 11 electrons.
The valence electrons are either lost to another atom or the sodium atom gains valence electrons, it really depends on if what the sodium atom is bonding with has a lot or a little of valence electrons. The structure doesn't change though, just the number of valence electrons change. The nucleus is never changed when an ion is formed.
it is 12
An atom of sodium has one valence electron. When a sodium atom loses this electron to another atom, it becomes a sodium ion.
A chloride ion has a larger radius than a sodium ion, because the chloride has an additional complete valence shell of electrons compared to a sodium ion, but a sodium atom has lost the only electron in this valence shell that the sodium atom ever included to form a sodium ion.
Sodium ionSodium, Na, becomes a single positive cation Na+
The sodium ion has less electrons than protons whereas the sodium atom has an equal amount of protons and electrons
A sodium atom has 11 electrons so the total charge of all the electrons in a sodium ion is -10.
Sodium loses one electron to form a Na+ ion. Sulfur gains two electrons to form a sulfide ion, S2-.
Assuming that you're talking about one sodium atom and that it's not charged,the number of electrons will have to be 11.Source:http://www.chemicalelements.com/elements/na.html
There are a total of 11 electrons in Sodium.
A sodium atom becomes a sodium ion, when a neutron is added to the nucleus.

Sodium atom has 11 electrons...whereas sodium ion has 10 electrons. Sodium ion is more stable because it has a complete octet(noble gas configuration-Neon) which makes it inert like noble gas. Sodium atom tends to lose the extra electron which is in 3-s shell to become stable.
