There are less electrons than protons in a positive ion. More information is needed to determine the exact number.
Here is an example:
How many electrons are in a carbon ion with a positive charge of positive 2e? There are 6 protons in carbon (since it is element number 6). Since it has a charge of +2, there will be 2 less electrons than protons, so the number of electrons would be 4.
The charge of a positive sodium ion is +1 C.
Scandium typically has 21 electrons in a neutral atom. In an Sc3+ ion, it loses 3 electrons, so the ion would have 18 electrons.
Sodium ions have a charge of 1+
an ion
The C4- ion has a total of 18 electrons. Carbon normally has 6 electrons, but the negative charge of -4 means that there are 4 extra electrons added to the ion.
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.
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 loses one electron to form a Na+ ion. Sulfur gains two electrons to form a sulfide ion, S2-.
When an electron is added to a unipositive ion, the resulting atom gains a negative charge and becomes a neutral atom. The electron neutralizes the positive charge of the ion, balancing the overall charge of the atom.
The number of electrons are required to predict the charge of the ion.
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
