None. The electrons are not in the nucleus for any atoms. They swirl around the nucleus in space but do not enter the nucleus. If electrons are squeezed into nuclei of atoms through gravity in supermassive star collapses, they fuse with protons and become neutrons. Sodium has 11 protons and usually 12 neutrons in their nuclei but no electrons.
Sodium has 11 electrons.
If the sodium atom is neutral (not an ion), it will have the same number of protons (11) as electrons. Therefore, a sodium atom with an atomic number of 11 will have 11 electrons when it is not an ion.
The sodium ion will be larger. Because magnesium has one more proton than sodium, its nuclei pull harder on the electrons, reducing the ion's radius. This means that the magnesium ion is smaller.
A sodium ion differs from a sodium atom in that the sodium ion has a missing electron electron. It has a positive charge, as opposed to the atom, which is neutral.
If you dont know this answer , well i dont either :0
Sodium has 11 electrons.
A sodium ion with the symbol Na+ has 10 electrons. Sodium normally has 11 electrons, but when it loses one electron to form a Na+ ion, it has 10 electrons.
When sodium becomes an ion, it loses one electron to fulfill the octet rule. A neutral sodium ion has 11 electrons, so an ion will have 10.
A sodium atom has 11 electrons so the total charge of all the electrons in a sodium ion is -10.
If the sodium atom is neutral (not an ion), it will have the same number of protons (11) as electrons. Therefore, a sodium atom with an atomic number of 11 will have 11 electrons when it is not an ion.
The atomic number of sodium is 11 which means it has 11 protons and 11 electrons.
Sodium ion (Na+) has 10 valence electrons and oxygen ion (O2-) has 8 valence electrons.
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
The number of electrons are required to predict the charge of the ion.
The ion Na+ has 11 protons, 12 neutrons, and 10 electrons. This is because sodium has an atomic number of 11, meaning it naturally has 11 protons and 11 electrons, but as an ion with a +1 charge, it has lost 1 electron.
The sodium ion has less electrons than protons whereas the sodium atom has an equal amount of protons and electrons
