it contains 1 more proton that electron.
It would lose an electron
The sodium atom is much bigger than a sodium cation with a plus 1 charge, because the "lost" electron of the ion had a higher principal quantum number than any remaining electron in the ion and therefore was distributed through a larger volume of space than any of the remaining electrons.
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.
The Na+ ion is a sodium atom that has lost an electron and therefore has a single positive charge. Because a neutral sodium atom has one valence electron, it will usually form such an ion when it enters a chemical compound.
Neon is isoelectronic with the sodium ion.
Sodium Atom
what does an atom have in common with an ion?
If you dont know this answer , well i dont either :0
When a sodium atom forms an ion, it loses one electron from its outer shell. This loss of an electron leaves the sodium atom with a positive charge, as it now has one more proton than electrons. This results in the formation of a sodium ion, specifically a sodium cation with a charge of +1.
While a sodium ion and neon atom both have 10 electrons they are of different elements as a neon atom has 10 protons while sodium has 11. As a result the neon atom is neutral while the sodium ion carries a positive charge. So neon can exist on its own as a gas while sodium ion needs a negative ion to balance its charge and form an ionic solid.
Sodium has 11 electrons.
Actually, when sodium forms an ionic bond with chlorine, the sodium atom donates one electron to chlorine, resulting in the formation of a positive sodium ion and a negative chloride ion. The sodium ion becomes Na+ and the chloride ion becomes Cl-.
