they are stable
Neon is a noble gas ... its valance shell is filled.
Neon is not reactive at all because it has a full p sublevel of electrons (8 valence electrons total). This is a very stable configuration, and as a result, neon is neither a reactant nor a product in normal chemical reactions.
Valance electrons means that the element has not reached the octet configuration and is therefore reactive the reactivity depends on the no. of valance electrons the more valance electrons the more unstable the atom is and the more reactive it is.The gasses like helium neon xenon are all inert which means they have an octet configuration and have no delocalised or valance electrons.
there are 8 electrons in the valence shell of neon
Neon's complete electron configuration is: 1s22s22p6 Therefore, normally, neon does not have any electrons in its third energy level. As you can see, neon is a noble gas with 8 electrons in its valance shell, and is therefore chemically stable and is unlikely to react.
Eight - it has a full outer shell of electrons.
there are 8 electrons in the valence shell of neon
There are 7, 8 and 10 protons in nitrogen, oxygen and neon respectively. Neon has 8 valence electrons and is stable. Nitrogen and oxygen have 5 and 6 valence electrons respectively are are reactive.
because they are both noble gases... the valance (or outermost electron shell) is full of electrons so neither argon nor neon need to get rid of or gain electrons. Essentially, both atoms do not need to react to become stable; they are already stable
these gases are the noble gases or inert gases. They are non reactive and have stable valence electrons
Neon completely filled orbitals / energy levels. It has 8 valence electrons and have stable electronic configuration. Hence it is chemically inert and generally do not form compounds under normal conditions. Neon is not the least reactive.... helium is.
