it contains 1 more proton that 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.
It would lose an electron
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.
If you dont know this answer , well i dont either :0
Sodium Atom
what does an atom have in common with an ion?
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.
lose an electron, forms Na+, sodium with a charge of plus one.
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-.
