Their electron configuration =)
The sodium ion has one more proton than neon and 2 more neutrons. It has a positive charge where neon is neutral but they both do have 10 electrons
A neutral sodium must lose one electron in order for the resulting sodium ion to have the same electron configuration as an atom of the element neon.
Sodium atom has 11 electrons...whereas sodium ion has 10 electrons. Sodium ion is more stable because it has a complete octet(noble gas configuration-Neon) which makes it inert like noble gas. Sodium atom tends to lose the extra electron which is in 3-s shell to become stable.
A sodium ion would have a charge on it, such as a positive charge, a cation, or a negative charge, an anion. Take your charge to be Na+1. This means that sodium is missing one electron, thus having one more proton giving it a positive charge. Na normally has 11 electrons, but this plus one knocks it down to 10. Neon at a neutral charge has 10 electrons. So, a sodium ion and neon atom have the same number of electrons (but only if the Na ion is +1 charge).
A sodium atom would lose a electron so it would become a Na+ ion
what does an atom have in common with an ion?
what does an atom have in common with an ion?
The Fluoride ion, neon atom, and sodium ion all have the same electron configuration and known as ISO-ELECTRONIC ions.
Neon is isoelectronic with the sodium 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.
Both fluoride ion and sodium ion are isoelectronic with neon. That means all have 10 electrons.
The sodium ion has one more proton than neon and 2 more neutrons. It has a positive charge where neon is neutral but they both do have 10 electrons
They all have full outer shells. in other words 8 electrons in the outer shell
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 sodium ion has one more proton than neon and 2 more neutrons. It has a positive charge where neon is neutral but they both do have 10 electrons
