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.
what does an atom have in common with an ion?
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.
A sodium ion is a sodium atom missing one electron. A chlorine ion is a chlorine atom with an extra electron. A salt molecule is a sodium ion stuck to a chlorine 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.
A sodium atom has a net charge of zero. A sodium ion has a net charge of 1+.
Neon is isoelectronic with the sodium ion.
A sodium atom becomes a sodium ion, when a neutron is added to the nucleus.

Sodium Atom
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.
A sodium atom would lose a electron so it would become a Na+ ion
sodium
A sodium ion is a sodium atom missing one electron. A chlorine ion is a chlorine atom with an extra electron. A salt molecule is a sodium ion stuck to a chlorine ion.
A sodium ion is smaller in diameter than a sodium atom.
The sodium ion has less electrons than protons whereas the sodium atom has an equal amount of protons and electrons
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.
