only thing i could find is that the atomic number is the same
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.
Neon is isoelectronic with the sodium ion.
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.
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-.
Sodium ionSodium, Na, becomes a single positive cation Na+
When the neutral atom of sodium lose an electron become the cation Na+.
Yes, the cation Na+.
The sodium atom loses its valence electron to the chlorine atom forming a positive sodium ion and a negative chloride ion. The two are attracted to each other because of their opposite charges.
