8
It has 8 valence electrons.
Neon has 8 valence electrons. Each electron shell can hold a maximum of 8 electrons, so the valence electrons are the electrons in the outermost shell. Neon is in the 8th column of the periodic table, so it has a full outer shell.
there are 8 electrons in the valence shell of neon
Valence electrons can determine the reactivity of the atom. An atom with a full shell of valence electrons, like neon, will be less reactive than an atom with only one electron in its valence shell, like sodium.

The neon family, also known as Group 18 on the periodic table, contains elements with 8 valence electrons. This includes elements such as helium, neon, argon, krypton, xenon, and radon. Valence electrons are the electrons in the outermost energy level of an atom.
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.
Neon's atomic number is 10. Thus, neutral neon has 10 protons and 10 electrons. Since neon is a noble gas, it has 8 valence electrons.
No, a neon-22 atom has the same number of electrons as a neon-20 atom, which is 10 electrons. The difference between neon-22 and neon-20 lies in their number of neutrons, with neon-22 having 12 neutrons and neon-20 having 10 neutrons.
An aluminum atom has three valence electrons and needs to give up all three to achieve a stable electron configuration similar to that of a neon atom, which has a full octet of eight valence electrons. By losing these three electrons, aluminum attains a stable, positively charged ion (Al³⁺), resembling the noble gas configuration of neon.
Neon has 10 electrons.More Information:Its atomic number is 10. implying that neon has 10 protons and 10 electrons.As it has 8 electrons in the outer most shell it is very stable and does not need any other atom to contribute or to share with. So the neon atom is able to exist alone which is why it is known as an inert gas.Neon has 3 stable isotopes: 20Ne, 21Ne, and 22Ne; and 16 additional isotopes that are radioactive and range from 16Ne to 34Ne. All sport the atomic number of 10.
The atomic number is the number of protons in an atom. The number of protons in an atom is what gives the atom its elemental identity. The number of neutrons can change resulting in different isotopes of the same element. The number of electrons can change, resulting in different valence states of the same element. If the number of protons changes, then an atom of neon is no longer neon. So the atomic number of neon is always 10, because neon always has 10 protons.
