the one that is completely filled
neon has completely filled energy levels and hence is generally chemically inert (or unreactive).
No. argon is chemically unreactive due to the presence of completely filled orbitals.
If all the electron orbitals are filled then the atom is inert. It will not chemically react with anything. If an atom has empty spaces in the outer orbit, it will react with other elements. Electrons from other elements can share positions in the outer orbits.
Helium has completely filled orbitals / energy levels and is chemically inert. So it has no chemically property.
Neon has completely filled orbitals. It is chemically inert and does not combine with other elements.
Yes. because, Noble gases have completely filled valence electrons, they are stable and chemically inert.
Noble gases have completely filled orbitals and are stable and chemically inert (non-reactive).
because they have completely filled outer most energy levels
Noble gases are chemically inert, meaning they are generally non-reactive with other elements. This is due to their stable electron configuration, with a full outer shell of electrons. This makes noble gases very useful in applications where a non-reactive atmosphere is required.
Noble gases have completely filled orbitals (octet of electrons), they are stable and chemically inert (non-reactive).
They are generally unreactive as their orbitals are completely filled.
Noble gases have completely filled orbitals, are stable and chemically inert (non-reactive). So generally they will not form compounds.
