Sodium is atomic number 11, while neon is atomic number 10. We would already expect sodium to be heavier, but the most common stable isotope of sodium has 12 neutrons, and the most common stable isotope of neon has only 10. Since the atomic weight can be approximated by the sum of neutrons and protons (and the number of protons is the atomic number), we can guess that sodium's atomic mass is 23 and neon's is 20.
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
Their electron configuration =)
neon!
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.
The element with atomic number 10 is Neon. Neon is a noble gas hence with a low reactivity.
sodium has more protons and neutrons. electrons have practically no mass, valence electrons are just outer orbital electrons. sodium has 11 protons, 11 electrons, and 12 neutrons. Mass is 23. neon has 10 protons, 10 electrons, and 10 neutrons. Mass is just 20. The neon atom has 10 protons and 10 neutrons for a mass number of 20. The sodium atom has 11 protons and 12 neutrons for a mass number of 23. The number of valence electrons has no bearing on mass number or atomic weight.

hey there buddie it because its an atom of a hydrogen molecule and its quite an angry felllo that sodium eh , whereas the neon is more calm and relaxed when it reacts
Neon is isoelectronic with the sodium ion.
what does an atom have in common with an ion?

neon
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.

neon!
The mass of 1 atom of neon is 20 amu. It doesn't form molecules
